Physics formulas needed to pass the exam. Physics formulas that are recommended to be learned and mastered well for successful passing of the exam

The session draws near, and it's time for us to move from theory to practice. Over the weekend, we sat down and thought that many students would like to have a selection of basic physical formulas on hand. Dry formulas with an explanation: brief, concise, nothing superfluous. A very useful thing when solving problems, you know. Yes, and at the exam, when exactly what was most brutally memorized the day before can "jump out" of the head, such a selection will serve an excellent service.

Most of the problems are usually assigned to the three most popular areas of physics. This Mechanics, thermodynamics and Molecular physics, electricity... Let's take them!

Basic formulas in physics - dynamics, kinematics, statics

Let's start with the simplest. A good old-fashioned favorite straight and steady motion.

Kinematic formulas:

Of course, let's not forget about the movement in a circle, and then move on to the dynamics and Newton's laws.

After the dynamics, it's time to consider the conditions for the equilibrium of bodies and liquids, i.e. statics and hydrostatics

Now we will give the basic formulas on the topic "Work and Energy". Where are we without them!

Basic formulas of molecular physics and thermodynamics

Let us finish the section of mechanics with formulas for vibrations and waves and move on to molecular physics and thermodynamics.

Efficiency, Gay-Lussac's law, Clapeyron-Mendeleev's equation - all these lovely formulas are collected below.

By the way! There is a discount for all our readers now. 10% on the .

Basic physics formulas: electricity

It's time to move on to electricity, although thermodynamics love it less. We start with electrostatics.

And, under the drum roll, we finish with the formulas for Ohm's law, electromagnetic induction and electromagnetic oscillations.

That's all. Of course, a whole mountain of formulas could be brought up, but this is useless. When there are too many formulas, you can easily get confused, and then completely melt the brain. We hope our cheat sheet for basic physics formulas will help you solve your favorite problems faster and more efficiently. And if you want to clarify something or did not find the required formula: ask the experts student service... Our authors keep hundreds of formulas in their heads and crack problems like nuts. Contact us, and soon any task will be too tough for you.

In order to successfully prepare for the CT in physics and mathematics, among other things, three important conditions must be met:

1. Explore all topics and complete all tests and tasks given in the training materials on this site. To do this, you need nothing at all, namely: to devote three to four hours every day to preparing for the CT in physics and mathematics, studying theory and solving problems. The fact is that CT is an exam, where it is not enough just to know physics or mathematics, you still need to be able to quickly and smoothly solve a large number of problems on different topics and of varying complexity. The latter can only be learned by solving thousands of problems.
2. Learn all formulas and laws in physics, and formulas and methods in mathematics. In fact, it is also very simple to do this, there are only about 200 necessary formulas in physics, and even a little less in mathematics. In each of these subjects there are about a dozen standard methods for solving problems of the basic level of complexity, which are also quite possible to learn, and thus, completely automatically and without difficulty, at the right time, solve most of the CG. After that, you will only have to think about the most difficult tasks.
3. Attend all three physics and mathematics rehearsal tests. Each RT can be visited twice to solve both options. Again, at the CT, in addition to the ability to quickly and efficiently solve problems, and knowledge of formulas and methods, it is also necessary to be able to properly plan the time, distribute forces, and most importantly, fill out the answer form correctly, without confusing either the numbers of answers and tasks, or your own surname. Also, during RT, it is important to get used to the style of posing questions in tasks, which on the CT may seem very unusual to an unprepared person.

Successful, diligent and responsible fulfillment of these three points, as well as responsible elaboration of the final training tests, will allow you to show excellent results on the CT, the maximum of what you are capable of.

Found a bug?

If you, as it seems to you, found an error in the training materials, please write about it by e-mail (). In the letter, indicate the subject (physics or mathematics), the title or number of the topic or test, the number of the problem, or the place in the text (page) where, in your opinion, there is an error. Also describe what the alleged error is. Your letter will not go unnoticed, the error will either be corrected, or you will be explained why it is not an error.

So, as they say, from elementary to complex. Let's start with kinetic formulas:

Let's also remember the movement in a circle:

Slowly but surely, we moved on to a more complex topic - to dynamics:

After the dynamics, you can go to statics, that is, to the conditions of equilibrium of bodies relative to the axis of rotation:

After statics, you can also consider hydrostatics:

Where can we go without the topic “Work, energy and power”. It is for her that many interesting, but difficult tasks are given. Therefore, one cannot do without formulas here:

Basic formulas of thermodynamics and molecular physics

The last topic in mechanics is “Oscillations and Waves”:

Now you can safely move on to molecular physics:

Basic formulas of electricity

For many students, the topic of electricity is more complex than the topic of thermodynamics, but it is just as important. So let's start with electrostatics:

Let's move on to constant electric current:

Electromagnetic induction is also an important topic for knowledge and understanding of physics. Of course, formulas on this topic are necessary:

And, of course, where is it without electromagnetic oscillations:

Basic formulas of optical physics

Moving on to the next section on physics - optics. Here are 8 basic formulas you need to know. Rest assured, optics tasks are common:

Basic formulas of the elements of the theory of relativity

And the last thing to know before the exam. Tasks on this topic come across less often than the previous ones, but there are:

Basic formulas of light quanta

These formulas often have to be used due to the fact that there are many problems on the topic "Light quanta". So let's take a look at them:

You can end there. Of course, there are still a huge number of formulas in physics, but you don't really need them.

These were the basic formulas of physics

In this article, we have prepared 50 formulas that will be needed for the exam in 99 cases out of 100.

Advice: Print out all the formulas and take them with you. While typing, you will one way or another look at the formulas, memorizing them. Plus, with the basic physics formulas in your pocket, you will feel much more confident on the exam than without them.

We hope you enjoyed our selection of formulas!

P.S. Have you had enough 50 formulas in physics, or does the article need to be supplemented? Write in the comments.
