The session is approaching, and it’s time for us to move from theory to practice. Over the weekend we sat down and thought that many students would benefit from having a selection of basic physical formulas. Dry formulas with explanation: short, concise, nothing superfluous. A very useful thing when solving problems, you know. And during an exam, when exactly what was memorized the day before might “jump out of your head,” such a selection will serve an excellent purpose.

The most problems are usually asked in the three most popular sections 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. The good old favorite straight and uniform movement.

Kinematics formulas:

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

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

Now we present the basic formulas on the topic “Work and Energy”. Where would we be without them?

Basic formulas of molecular physics and thermodynamics

Let's finish the mechanics section with formulas for oscillations and waves and move on to molecular physics and thermodynamics.

The efficiency factor, the Gay-Lussac law, the Clapeyron-Mendeleev equation - all these formulas dear to the heart are collected below.

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

Basic formulas in physics: electricity

It's time to move on to electricity, even though it is less popular than thermodynamics. Let's start with electrostatics.

And, to the beat of the drum, we end with formulas for Ohm’s law, electromagnetic induction and electromagnetic oscillations.

That's all. Of course, a whole mountain of formulas could be cited, but this is of no use. When there are too many formulas, you can easily get confused and even melt your brain. We hope our cheat sheet of basic physics formulas will help you solve your favorite problems faster and more efficiently. And if you want to clarify something or haven’t found the right 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 up to you.

They are absolutely necessary so that a person who decides to study this science, armed with them, can feel like a fish in water in the world of physics. Without knowledge of formulas, solving problems in physics is unthinkable. But it is almost impossible to remember all the formulas and it is important to know, especially for a young mind, where to find this or that formula and when to apply it.

The location of physical formulas in specialized textbooks is usually distributed among the corresponding sections among textual information, so searching for them there can take quite a lot of time, and even more so if you suddenly need them urgently!

Featured below physics cheat sheets contain all the basic formulas from the physics course, which will be useful to students of schools and universities.

As a rule, it is mathematics, and not physics, that is considered to be the queen of the exact sciences. We believe that this statement is controversial, because technical progress impossible without knowledge of physics and its development. Due to its complexity, it is unlikely to ever be included in the list of mandatory state exams, but, one way or another, applicants for technical specialties have to take it without fail. The most difficult thing is to remember the numerous laws and formulas in physics for the Unified State Exam; we will talk about them in this article.

Secrets of preparation

Perhaps this is due to the apparent complexity of the subject or the popularity of professions in the humanities and management, but in 2016 only 24% of all applicants decided to take physics, in 2017 - only 16%. Such statistics involuntarily make one wonder whether the requirements are too high or whether the level of intelligence in the country is simply falling. For some reason I can’t believe that so few 11th grade students want to become:

engineers;
jewelers;
aircraft designers;
geologists;
pyrotechnicians;
ecologists,
production technologists, etc.

Knowledge of the formulas and laws of physics is equally necessary for developers of intelligent systems, computer technology, equipment and weapons. At the same time, everything is interconnected. For example, specialists producing medical equipment, at one time we studied an in-depth course in atomic physics, because without isotope separation, we will have neither X-ray equipment nor radiation therapy. Therefore, the creators of the Unified State Exam tried to take into account all the topics of the school course and, it seems, did not miss a single one.

Those students who regularly attended all physics lessons up to last call, they know that in the period from grades 5 to 11, about 450 formulas are studied. It is extremely difficult to single out at least 50 of these four and a half hundred, since they are all important. The developers of the Codifier obviously also adhere to a similar opinion. However, if you are unusually gifted and not limited in time, 19 formulas will be enough for you, because if you wish, you can derive all the rest from them. We decided to take the main sections as a basis:

mechanics;
molecular physics;
electromagnetism and electricity;
optics;
atomic physics.

Obviously, preparation for the Unified State Exam should be daily, but if for some reason you have started studying all the material only now, a real miracle can be accomplished by the express course offered by our center. We hope these 19 formulas will also be useful to you:

You probably noticed that some physics formulas for passing the Unified State Exam left without explanation? We leave it to you to study them yourself and discover the laws by which absolutely everything is done in this world.
