THE PHYSICS CLASSROOM TUTORIAL

A set of instructional pages written in an easy-to-understand language and complemented by graphics and Check Your Understanding sections. An ideal starting location for those grasping for understanding or searching for answers.

PHYSICS SIMULATIONS

The Physics Interactives includes a large collection of HTML5 interactive physics simulations. Designed with tablets such as the iPad and with Chromebooks in mind, this user-friendly section is filled with skill-building exercises, physics simulations, and game-like challenges.

PHYSICS VIDEO TUTORIAL

Our Video Tutorial provides a video-based alternative to the written Tutorial above. We aim to present relatively short, highly-organized presentations with a strong graphical component on discrete topics. Watch them on our site or follow the links to YouTube. We add videos quite frequently so stop back by if you don't find what you are looking for. Or subscribe to our YouTube channel,  tap the bell , and receive notifications when new videos come out.

MULTIMEDIA PHYSICS STUDIOS

A large collection of GIF animations and QuickTime movies designed to demonstrate physics principles in a visual manner. Each animation is accompanied by explanations and links to further information.

CONCEPT BUILDERS

Have you tried a Concept Builder lately? You should. This growing collection of cognitively-rich exercises will focus student attention on discrete learning goals. Filled with interactive elements, this section is the perfect tool for getting students thinking about the meaning of concepts. Perfect for students and 1:1 classrooms using iPads, Chromebooks, and the like. And for Chemistry types, we've added a large collection of Chemistry Concept Builders. 

MINDS ON PHYSICS - VERSION 5   

Minds On Physics - Version 5 is the HTML5 version of Minds On Physics that replaces our App and Legacy versions. Relying on a large bank of carefully crafted questions, Minds On Physics seeks to improve students' conceptions of physics. "MOPs" combines interactive questioning modules with a thorough, question-specific Help system to engage students in an exercise in thinking, reflecting and learning. Version 5 is our best-yet version of Minds On Physics. There is a fully functional free version and a paid version that integrates seamlessly with our Task Tracker system and offers some rather enticing features.  

THE CALCULATOR PAD

Version 2 of the Calculator Pad is now available. Our newest version includes >2500 Physics and Chemistry problems organized into >250 ready-to-use problem sets. Numerical information is randomly-generated. An answer box allows students to solve and check their answers. Most problems are accompanied  by an audio-guided solution that explains how to solve a similar problem while hilighting the habits that can be adopted for solving any problem. Teachers with Task Tracker accounts can modify problems and problem sets and even create their own problems. Task Tracker also allows teachers to assign problems to their students and track their progress. 

CONCEPT CHECKERS    

Concept Checkers were built to coordinate with the Physics Interactives section of our website. Relying upon our Task Tracker tool to deliver questions, check answers, and track student progress, a Concept Checker is designed to coordinate with an interactive simulation. Use it as a follow-up check to understanding after exploring the simulation. Most sims are accompanied by a Concept Checker. Some sims have Task Tracker code built into the simulation. But not all sims will have a Concept Checker.  Concept Checkers can be used with or without a Task Tracker account. 

THE SCIENCE REASONING CENTER

The Science Reasoning Center is our most recent upgrade. This section includes about 70 activities that are perfect for encouraging scientific reasoning skills. Students use science and engineering practices, combined with cross cutting science concepts and core ideas from the disciplines of physics (and chemistry) to analyze phenomenon, experiments, and data presentations. We broke ground in April of 2023; we will continue work throughout the 2023-24 school year.

THE REVIEW SESSION

A collection of pages with questions and answers/explanations which serve as reviews or practice. Each review complements a chapter from The Physics Classroom Tutorial.

PHYSICS HELP

A variety of question-and-answer pages which target specific concepts and skills. Topics range from the graphical analysis of motion and drawing free body diagrams to a discussion of vectors and vector addition.

ACT TEST CENTER

Calling all high school juniors: You've trusted The Physics Classroom to help prepare you for that unit exam in physics. Why not trust us to help prepare you for the biggest test of the year - the ACT test? That's right. Let the TPC help you with the ACT.

Pencil Ruler

CURRICULUM CORNER

A collection of classroom ready worksheets for use by teachers with their classes. Pages are synchronized to readings from The Physics Classroom Tutorial and to assignments of The Minds On Physics Internet Modules. And now teachers can purchase The Solutions Guide containing complete answers, explanations and solutions to all worksheets. This is a section of great usefulness to teachers and of little interest to students. The Solutions Guide is available as a Digital Download.

TEACHER PRESENTATION PACK

Our Teacher Presentation Pack is a downloadable product that includes nearly 190 Microsoft PowerPoint slide decks, about 170 animations and videos in .mp4 and .gif formats, too-many-to-count stand-alone images, and a Lesson Notes page for every slide deck. The slide decks are compatible with Google Slides. We did our best to make the product ready-to-use and at the same time fully customizable. It's a great tool in the toolbox for any early-career teacher, cross-over teacher, or even veteran teacher.

QUESTION BANK

Writing good tests and quizzes for your physics class just got a whole lot easier! With The Physics Classroom's Question Bank, physics teachers can quickly put together multiple choice and free-response quizzes and tests that target concepts discussed at The Physics Classroom website. The Question Bank is available for purchase as a both a CD resource and as a Digital Download. Use of the Question Bank requires the Microsoft Word application. (Answers are NOT included on the Question Bank.)

NGSS CORNER

Our newest section, the NGSS Corner assists teachers of Physics and Physical Science in aligning their curricula with the Next Generation Science Standards. Numerous resources are identified and their alignment with the NGSS is described.

TEACHER TOOLKITS

The Teacher Toolkits provide teachers with packages of online resources (simulations, movies, animations, demonstration ideas, etc.) that are organized around a topic and a set of learning objectives. These resources, when combined with the numerous resources on our own site, allow teachers to plan high-quality, engaging instruction and to map out a curriculum that is NGSS-based.

THE LABORATORY

While you explore the approximately 150 labs here at The Laboratory, you will likely generate some questions about how they are used and how you can use them. This page, and the pages it links to, are hoped to provide some answers to those questions.

THE PHOTO GALLERY

The Photo Gallery provides teachers a toolbox of physics-relevant photos from the wealth of photos on Flickr. The Photo Gallery offers teachers three things: access to photos, organized by topic; a collection of nearly 30 galleries; and an invitation to join this exciting project of capturing and sharing physics phenomenon with a camera. Of course, students are welcome to participate as well.

Learning Objectives

By the end of this section, you will be able to:

  • Explain the difference between a principle and a law.
  • Explain the difference between a model and a theory.

The physical universe is enormously complex in its detail. Every day, each of us observes a great variety of objects and phenomena. Over the centuries, the curiosity of the human race has led us collectively to explore and catalog a tremendous wealth of information. From the flight of birds to the colors of flowers, from lightning to gravity, from quarks to clusters of galaxies, from the flow of time to the mystery of the creation of the universe, we have asked questions and assembled huge arrays of facts. In the face of all these details, we have discovered that a surprisingly small and unified set of physical laws can explain what we observe. As humans, we make generalizations and seek order. We have found that nature is remarkably cooperative—it exhibits the underlying order and simplicity we so value.

It is the underlying order of nature that makes science in general, and physics in particular, so enjoyable to study. For example, what do a bag of chips and a car battery have in common? Both contain energy that can be converted to other forms. The law of conservation of energy (which says that energy can change form but is never lost) ties together such topics as food calories, batteries, heat, light, and watch springs. Understanding this law makes it easier to learn about the various forms energy takes and how they relate to one another. Apparently unrelated topics are connected through broadly applicable physical laws, permitting an understanding beyond just the memorization of lists of facts.

The unifying aspect of physical laws and the basic simplicity of nature form the underlying themes of this text. In learning to apply these laws, you will, of course, study the most important topics in physics. More importantly, you will gain analytical abilities that will enable you to apply these laws far beyond the scope of what can be included in a single book. These analytical skills will help you to excel academically, and they will also help you to think critically in any professional career you choose to pursue. This module discusses the realm of physics (to define what physics is), some applications of physics (to illustrate its relevance to other disciplines), and more precisely what constitutes a physical law (to illuminate the importance of experimentation to theory).

Science and the Realm of Physics

Science consists of the theories and laws that are the general truths of nature as well as the body of knowledge they encompass. Scientists are continually trying to expand this body of knowledge and to perfect the expression of the laws that describe it. Physics is concerned with describing the interactions of energy, matter, space, and time, and it is especially interested in what fundamental mechanisms underlie every phenomenon. The concern for describing the basic phenomena in nature essentially defines the realm of physics .

Physics aims to describe the function of everything around us, from the movement of tiny charged particles to the motion of people, cars, and spaceships. In fact, almost everything around you can be described quite accurately by the laws of physics. Consider a smart phone ( Figure 1.3 ). Physics describes how electricity interacts with the various circuits inside the device. This knowledge helps engineers select the appropriate materials and circuit layout when building the smart phone. Next, consider a GPS system. Physics describes the relationship between the speed of an object, the distance over which it travels, and the time it takes to travel that distance. GPS relies on precise calculations that account for variations in the Earth's landscapes, the exact distance between orbiting satellites, and even the effect of a complex occurrence of time dilation. Most of these calculations are founded on algorithms developed by Gladys West, a mathematician and computer scientist who programmed the first computers capable of highly accurate remote sensing and positioning. When you use a GPS device, it utilizes these algorithms to recognize where you are and how your position relates to other objects on Earth.

Applications of Physics

You need not be a scientist to use physics. On the contrary, knowledge of physics is useful in everyday situations as well as in nonscientific professions. It can help you understand how microwave ovens work, why metals should not be put into them, and why they might affect pacemakers. (See Figure 1.4 and Figure 1.5 .) Physics allows you to understand the hazards of radiation and rationally evaluate these hazards more easily. Physics also explains the reason why a black car radiator helps remove heat in a car engine, and it explains why a white roof helps keep the inside of a house cool. Similarly, the operation of a car’s ignition system as well as the transmission of electrical signals through our body’s nervous system are much easier to understand when you think about them in terms of basic physics.

Physics is the foundation of many important disciplines and contributes directly to others. Chemistry, for example—since it deals with the interactions of atoms and molecules—is rooted in atomic and molecular physics. Most branches of engineering are applied physics. In architecture, physics is at the heart of structural stability, and is involved in the acoustics, heating, lighting, and cooling of buildings. Parts of geology rely heavily on physics, such as radioactive dating of rocks, earthquake analysis, and heat transfer in the Earth. Some disciplines, such as biophysics and geophysics, are hybrids of physics and other disciplines.

Physics has many applications in the biological sciences. On the microscopic level, it helps describe the properties of cell walls and cell membranes ( Figure 1.6 and Figure 1.7 ). On the macroscopic level, it can explain the heat, work, and power associated with the human body. Physics is involved in medical diagnostics, such as x-rays, magnetic resonance imaging (MRI), and ultrasonic blood flow measurements. Medical therapy sometimes directly involves physics; for example, cancer radiotherapy uses ionizing radiation. Physics can also explain sensory phenomena, such as how musical instruments make sound, how the eye detects color, and how lasers can transmit information.

It is not necessary to formally study all applications of physics. What is most useful is knowledge of the basic laws of physics and a skill in the analytical methods for applying them. The study of physics also can improve your problem-solving skills. Furthermore, physics has retained the most basic aspects of science, so it is used by all of the sciences, and the study of physics makes other sciences easier to understand.

Models, Theories, and Laws; The Role of Experimentation

The laws of nature are concise descriptions of the universe around us; they are human statements of the underlying laws or rules that all natural processes follow. Such laws are intrinsic to the universe; humans did not create them and so cannot change them. We can only discover and understand them. Their discovery is a very human endeavor, with all the elements of mystery, imagination, struggle, triumph, and disappointment inherent in any creative effort. (See Figure 1.8 and Figure 1.9 .) The cornerstone of discovering natural laws is observation; science must describe the universe as it is, not as we may imagine it to be.

We all are curious to some extent. We look around, make generalizations, and try to understand what we see—for example, we look up and wonder whether one type of cloud signals an oncoming storm. As we become serious about exploring nature, we become more organized and formal in collecting and analyzing data. We attempt greater precision, perform controlled experiments (if we can), and write down ideas about how the data may be organized and unified. We then formulate models, theories, and laws based on the data we have collected and analyzed to generalize and communicate the results of these experiments.

A model is a representation of something that is often too difficult (or impossible) to display directly. While a model is justified with experimental proof, it is only accurate under limited situations. An example is the planetary model of the atom in which electrons are pictured as orbiting the nucleus, analogous to the way planets orbit the Sun. (See Figure 1.10 .) We cannot observe electron orbits directly, but the mental image helps explain the observations we can make, such as the emission of light from hot gases (atomic spectra). Physicists use models for a variety of purposes. For example, models can help physicists analyze a scenario and perform a calculation, or they can be used to represent a situation in the form of a computer simulation. A theory is an explanation for patterns in nature that is supported by scientific evidence and verified multiple times by various groups of researchers. Some theories include models to help visualize phenomena, whereas others do not. Newton’s theory of gravity, for example, does not require a model or mental image, because we can observe the objects directly with our own senses. The kinetic theory of gases, on the other hand, is a model in which a gas is viewed as being composed of atoms and molecules. Atoms and molecules are too small to be observed directly with our senses—thus, we picture them mentally to understand what our instruments tell us about the behavior of gases.

A law uses concise language to describe a generalized pattern in nature that is supported by scientific evidence and repeated experiments. Often, a law can be expressed in the form of a single mathematical equation. Laws and theories are similar in that they are both scientific statements that result from a tested hypothesis and are supported by scientific evidence. However, the designation law is reserved for a concise and very general statement that describes phenomena in nature, such as the law that energy is conserved during any process, or Newton’s second law of motion, which relates force, mass, and acceleration by the simple equation F = m a F = m a . A theory, in contrast, is a less concise statement of observed phenomena. For example, the Theory of Evolution and the Theory of Relativity cannot be expressed concisely enough to be considered a law. The biggest difference between a law and a theory is that a theory is much more complex and dynamic. A law describes a single action, whereas a theory explains an entire group of related phenomena. And, whereas a law is a postulate that forms the foundation of the scientific method, a theory is the end result of that process.

Less broadly applicable statements are usually called principles (such as Pascal’s principle, which is applicable only in fluids), but the distinction between laws and principles often is not carefully made.

Models, Theories, and Laws

Models, theories, and laws are used to help scientists analyze the data they have already collected. However, often after a model, theory, or law has been developed, it points scientists toward new discoveries they would not otherwise have made.

The models, theories, and laws we devise sometimes imply the existence of objects or phenomena as yet unobserved. These predictions are remarkable triumphs and tributes to the power of science. It is the underlying order in the universe that enables scientists to make such spectacular predictions. However, if experiment does not verify our predictions, then the theory or law is wrong, no matter how elegant or convenient it is. Laws can never be known with absolute certainty because it is impossible to perform every imaginable experiment in order to confirm a law in every possible scenario. Physicists operate under the assumption that all scientific laws and theories are valid until a counterexample is observed. If a good-quality, verifiable experiment contradicts a well-established law, then the law must be modified or overthrown completely.

The study of science in general and physics in particular is an adventure much like the exploration of uncharted ocean. Discoveries are made; models, theories, and laws are formulated; and the beauty of the physical universe is made more sublime for the insights gained.

The Scientific Method

Ibn al-Haytham (sometimes referred to as Alhazen), a 10th-11th century scientist working in Cairo, significantly advanced the understanding of optics and vision. But his contributions go much further. In demonstrating that previous approaches were incorrect, he emphasized that scientists must be ready to reject existing knowledge and become "the enemy" of everything they read; he expressed that scientists must trust only objective evidence. Al-Haytham emphasized repeated experimentation and validation, and acknowledged that senses and predisposition could lead to poor conclusions. His work was a precursor to the scientific method that we use today.

As scientists inquire and gather information about the world, they follow a process called the scientific method . This process typically begins with an observation and question that the scientist will research. Next, the scientist typically performs some research about the topic and then devises a hypothesis. Then, the scientist will test the hypothesis by performing an experiment. Finally, the scientist analyzes the results of the experiment and draws a conclusion. Note that the scientific method can be applied to many situations that are not limited to science, and this method can be modified to suit the situation.

Consider an example. Let us say that you try to turn on your car, but it will not start. You undoubtedly wonder: Why will the car not start? You can follow a scientific method to answer this question. First off, you may perform some research to determine a variety of reasons why the car will not start. Next, you will state a hypothesis. For example, you may believe that the car is not starting because it has no engine oil. To test this, you open the hood of the car and examine the oil level. You observe that the oil is at an acceptable level, and you thus conclude that the oil level is not contributing to your car issue. To troubleshoot the issue further, you may devise a new hypothesis to test and then repeat the process again.

The Evolution of Natural Philosophy into Modern Physics

Physics was not always a separate and distinct discipline. It remains connected to other sciences to this day. The word physics comes from Greek, meaning nature. The study of nature came to be called “natural philosophy.” From ancient times through the Renaissance, natural philosophy encompassed many fields, including astronomy, biology, chemistry, physics, mathematics, and medicine. Over the last few centuries, the growth of knowledge has resulted in ever-increasing specialization and branching of natural philosophy into separate fields, with physics retaining the most basic facets. (See Figure 1.11 , Figure 1.12 , and Figure 1.13 .) Physics as it developed from the Renaissance to the end of the 19th century is called classical physics . It was transformed into modern physics by revolutionary discoveries made starting at the beginning of the 20th century.

Classical physics is not an exact description of the universe, but it is an excellent approximation under the following conditions: Matter must be moving at speeds less than about 1% of the speed of light, the objects dealt with must be large enough to be seen with a microscope, and only weak gravitational fields, such as the field generated by the Earth, can be involved. Because humans live under such circumstances, classical physics seems intuitively reasonable, while many aspects of modern physics seem bizarre. This is why models are so useful in modern physics—they let us conceptualize phenomena we do not ordinarily experience. We can relate to models in human terms and visualize what happens when objects move at high speeds or imagine what objects too small to observe with our senses might be like. For example, we can understand an atom’s properties because we can picture it in our minds, although we have never seen an atom with our eyes. New tools, of course, allow us to better picture phenomena we cannot see. In fact, new instrumentation has allowed us in recent years to actually “picture” the atom.

Limits on the Laws of Classical Physics

For the laws of classical physics to apply, the following criteria must be met: Matter must be moving at speeds less than about 1% of the speed of light, the objects dealt with must be large enough to be seen with a microscope, and only weak gravitational fields (such as the field generated by the Earth) can be involved.

Some of the most spectacular advances in science have been made in modern physics. Many of the laws of classical physics have been modified or rejected, and revolutionary changes in technology, society, and our view of the universe have resulted. Like science fiction, modern physics is filled with fascinating objects beyond our normal experiences, but it has the advantage over science fiction of being very real. Why, then, is the majority of this text devoted to topics of classical physics? There are two main reasons: Classical physics gives an extremely accurate description of the universe under a wide range of everyday circumstances, and knowledge of classical physics is necessary to understand modern physics.

Modern physics itself consists of the two revolutionary theories, relativity and quantum mechanics. These theories deal with the very fast and the very small, respectively. Relativity must be used whenever an object is traveling at greater than about 1% of the speed of light or experiences a strong gravitational field such as that near the Sun. Quantum mechanics must be used for objects smaller than can be seen with a microscope. The combination of these two theories is relativistic quantum mechanics, and it describes the behavior of small objects traveling at high speeds or experiencing a strong gravitational field. Relativistic quantum mechanics is the best universally applicable theory we have. Because of its mathematical complexity, it is used only when necessary, and the other theories are used whenever they will produce sufficiently accurate results. We will find, however, that we can do a great deal of modern physics with the algebra and trigonometry used in this text.

Check Your Understanding

A friend tells you they have learned about a new law of nature. What can you know about the information even before your friend describes the law? How would the information be different if your friend told you they had learned about a scientific theory rather than a law?

Without knowing the details of the law, you can still infer that the information your friend has learned conforms to the requirements of all laws of nature: it will be a concise description of the universe around us; a statement of the underlying rules that all natural processes follow. If the information had been a theory, you would be able to infer that the information will be a large-scale, broadly applicable generalization.

What Is Physics?

Table of Contents

When we look at the things around us, many questions are in our minds. Physics gives the answers to all these questions. You all must have heard about chemistry and biology. There are a lot of applications of physics with different aspects of nature.

assignment of physics

Chemistry tells us about the results of things, and biology studies the processes of real life. But only physics tells us how things work. And if you need chemistry assignment help , you can contact our experts. 

For example: As you look at a car running on the road, the question comes to your mind how does this car run on the road, how does its engine work, and how does a small brake pedal stop the entire car? The answer to all these questions is physics. Also, angular momentum is part of physics.

Physics tells us how things work. Many physics topics help us to understand the concept of nature and the universe. From the galaxy to the small atom, we can understand all these through physics.

The term physics is derived from the Greek word PHUSIKE, which means nature and its study. Energy, force, light, and time are all very basic concepts that we study in physics.

What Are The Topics Of Basic Physics?

These are the following topics of basic physics, and it is such as;

Subject Matter Topics for Introductory Physics

The following are the subject matter topics for introductory physics. It is also the best Physics topics for College students.

Reasons: Why do students choose to study physics in their higher education?

A physics degree helps you explore the world in every aspect- from the galaxy and the small atom with electronic structure. It equips you with techniques that help you to solve complex problems. It lets you know about some beautiful things and the plain ugly truth that rule our world. In reality, analyzing physics provides you with a deep knowledge of how the world works.

Newton’s Laws of Motion

Newton’s Law is One of the Most Important Physics Topics. Newton’s Law of Motion consists of three laws, based on which all things related to motion can be known. Newton’s law of motion consists of three laws. From these laws, we can know all things related to motion.

The first law of Newton’s law states Uniform Motion and is also called the Law of inertia. In the second Newton’s Law, the force is said to be, which is directly proportional to the square of acceleration. And in the third Newton’s law, it is said that every action has an equal and opposite reaction.

These three newton’s law of motion is a very important part of physics topics. If you are studying physics, then definitely read this topic, if any problem arises, you can take help related to physics assignments and homework from our experts.

Vectors and Projectiles

Vectors and Projectiles are one of the third most important physics topics. Vectors and projectiles both have different meanings, but they are related to each other, only then they are considered to be the same topic.

Arrows represent vectors. The length of the Arrow is Proportional to the Magnitude, and the Direction of the Arrow is to be the Direction of the Vector that defines the vector. And projectile means that after throwing any object, it goes down due to gravity.

This is a very interesting topic, if you are a student of physics, then you must read this topic, and if you need help with any assignment or homework related to it, then you can take it from our experts.

Work and Energy

Work and energy are the two words that we often use in everyday life, but this is a very important physics topic. Work and energy have different meanings in physics.

Work means that energy is transferred by force, and energy means the ability to work. Each other’s words are fulfilling the meaning of these two. It is a very interesting physics topic, on top of which you can also write many assignments.

Circular Motion and Gravitation

Circular Motion and Gravitation are very interesting physics topics. It is said that forces can be used in circular motion and gravitation.

Circular motion means when a body moves in a circular path at a content speed and constant direction. And gravitation means that if we throw an object upwards, that object will go back to the top of the force according to the Cause of Gravity.

Electric circuits are one of the physics topics that tell us in detail about electric circuits. Both positive and negative are electric field circuits. This is explained by what works and how they work.

Electric circuits refer to the positive current coming out of a cell and generator with a wire connected to the negative circuit with the help of a wire. This is a very interesting chapter for physics students and can also offer many models and assignments on this topic.

Thermal physics is also a very important part of physics topics. Thermal physics is a topic that exposes students to many new things.

The study of thermal physics is done by heat. Heat energy and thermal energies are the motions and vibrations of molecules in terms of the energy activity of any substance or system. If there are more molecules in it, the same energy will be found in it. This is a very interesting topic for students, and many assignments can be made on it.

Vibrations and Waves

Vibrations and Waves On hearing this word, your mind must have heard thoughts related to the sound. But vibrations and waves are also part of physics topics. Vibrations and waves are very important in physics. Also, know How do convex mirrors impact your reflection?

Vibrations mean that if we shake with a big pay force, then that body keeps vibrating for some time due to that force, that vibration is called vibration. A wave can be described as a disturbance that travels from one medium to another through a medium. They are both from advance quantum physics , and students can make many models and assignments on them to get the aim of physics.

Assignment help

Refraction and Lenses

Refraction and lenses are some of the most interesting and important physics topics. All this topic is based on refraction and lenses. Students need to know how light lanes affect refraction through their theoretical physicist.

Physics captures our daily life. It explains the motion, forces, and internal energy behind ordinary works. For example, various actions like driving a car, walking, or using a phone call include advances in physics.

Let’s understand it through examples-

1. Example of heat

Heat is a kind of energy that carries from a warm object to a cold object. For example, when you use the stove for cooking, the flame transfers the heat to the utensil put on top of it. As a result, food gets heat from utensils. Physical optics must account for the more subtle properties of visible light in its waveform.

2. Example of a ballpoint pen

The use of a ballpoint pen is inevitable whether you are in school or at the workplace. If physics is not there, then you are not able to write on paper. The physics topics of gravity come when we talk about writing through a ballpoint pen.

As you press the pen on the paper to write, the ball turns, or gravity pushes the ink down on the ball top, from where it is transferred to the paper.

Write Assignment of Physics | Summer assignment help

Assignment is the best way to test student’s knowledge. Most of the schools, colleges provide assignment to their students. An assignment sheet contains theoretical questions as well as numerical problems. Students need to solve those questions and numerical problems as a homework. Many of the students do not know the correct way to solve the assignments and they fail to secure a good marks. In this article, I am going to share with you how to write the assignment of Physics? How can you get helps from assignment solving experts?

Contents in this article:

How do you write an Assignment in Physics?

  • Physics assignment help

Writing an assignment of physics is not too hard. You need to solve the assignment and then write it. But the correct solutions within the due time and the decoration of assignment sheets are the important things to take care of. Here, I am sharing some useful tips to write assignments.

Correct solutions of questions

The most important thing is to solve all the questions and problems correctly. Because, the decoration and writing will not be beneficial if the solutions are not correct.

After solving all the questions, revise the answer sheet twice.

Font size and page numbering

If you are writing assignment Microsoft Word, then you may think about the correct font and line spacing. You should check whether there is any instruction given by the intuition or not. If there is no such instruction, then you can use any font and line spacing. But, the font and the size of letter should look good and easy to read.

You can use the font Calibri (Body) with font size 13 . Line spacing should be default which is 1.08 pt . Keep the page margins default. Students should number each pages after the index page.

Physics assignment front page

Front page or the cover page of physics assignment should be attractive. Followings are important for this –

Physics Assignment Front page Sample

  • Use colorful page.
  • Page should be thicker.
  • Write the title of the assignment at the top of the front page with a font 28 or 30.
  • Your name and roll number will be at the middle of the page.
  • Use one or two photos related to Physics at the bottom of the cover page.

Acknowledgement page

The first page of the assignment paper should be acknowledgement page. The student should acknowledge his/her teachers, institute and parents for their motivations and teaching skills.

The second page should be index page. This page gives a clear indication that the answer to which question is written on which page. This makes easier to the teacher to find a random answer from your assignment paper.

Answers to the Assignment of Physics

Students should write the answers to the assignment one by one after the index page. These pages of answers should be numbered as 1, 2, 3,..etc. It is better to write the question with question number before writing the answer for that question. The font and font size are already mentioned above.
