Tips on how to remember all the forces in physics

Everything that happens in our world is due to the influence of certain forces in physics. And you will have to learn each of them, if not at school, then at the institute for sure.

Of course, you can try to memorize them. But it will be much faster, more fun and more interesting just to realize the essence of each physical force as it interacts with the environment.

Forces in nature and fundamental interactions
There are many forces. The force of Archimedes, the force of gravity, the force of Ampere, the force of Lorentz, Coreolis , the force of friction-rolling , etc. Actually, it is impossible to learn all the forces, since not all of them are still open. But this is also very important - without exception, all forces known to us can be reduced to the manifestation of the so-called fundamental physical interactions .

There are 4 fundamental physical interactions in nature. It would be more accurate to say that people know 4 fundamental interactions, and at the moment no other interactions have been found. What are these interactions?

Gravitational interaction
Electromagnetic interaction
Strong interaction
Weak interaction

So, gravity is a manifestation of gravitational interaction. Most of the mechanical forces (frictional force, elastic force) are the result of electromagnetic interaction. The strong interaction holds the nucleons of the atomic nucleus together, preventing the nucleus from decaying. Weak interaction forces free elementary particles to disintegrate. Thus, electromagnetic and weak interactions are combined in electroweak aboe interaction .

The possible fifth fundamental interaction (after the discovery of the Higgs boson ) is called the Higgs field . But in this area is studied is so small that we do not jump to conclusions, but rather wait for that will tell us ucheny e . Although there is laboratory work on these subjects, and they need to be addressed. If you, like scientists, still know this area poorly, you can always ask for help in physics https://essayassistant.org/physics-help/.

Tips on how to remember all the forces in physics
There are two ways to learn the laws of physics.

The first is to stupidly learn meanings, definitions, formulas. A significant drawback of this method is that it is unlikely to help answer additional questions from the teacher. There is another important disadvantage of this method - having learned in this way, you will not get the most important thing: understanding. As a result, memorizing a rule / formula / law, or whatever it may be, allows you to acquire only fragile, short-term knowledge of the topic.

The second way is understanding the material being studied. But is it so easy to understand what is (in your opinion) impossible to understand?

Yes, there is a solution to this terribly difficult but solvable problem! Here are some ways to learn all the forces in physics (and in general in any other subject):

To know all the forces of physics, when studying them, you need to find real life examples in which these forces are involved. For example, what can be understood by the force of gravity (physics)? All thrown objects always fall down - a perfect example of the real action of gravity. Or an example of the weight that all objects have - this is also nothing more than the force of gravitational influence. With a person weighing 70 kg, he acts on a support (earth, asphalt, floor, scales) with a force of 70 kg, which arises within the gravitational field of our planet.

To know physical strengths, it is not necessary to memorize them: you need to begin to understand them

It is quite logical that on other planets the force of gravity will be completely different, which means that the weight of objects will also differ. What is the weight in this case? The weight will be equal to the mass multiplied by the acceleration due to gravity. The acceleration due to gravity itself is measured in meters per second squared. This indicator is different for different planets. For ours, for example, this figure is 9.8 meters per second. The moon has 1.6. The acceleration of the fall is a characteristic of the force with which the planet will attract bodies to itself.

On a note!

It is important to remember and know all physical forces (well, or learn the entire list of them in physics) in order to avoid embarrassing misunderstandings. Remember that body mass is not its weight, but a measure of its inertia. For example, in weightlessness, bodies have no weight, because there is no gravity. But if you want to move the body in weightlessness from its place, you will have to act on it with a certain force. And the higher the body weight, the more force you will have to use.

If you can imagine how a person's weight can change depending on the choice of the planet, you will be able to quickly understand the concept of gravitational force, with the concepts of weight and mass, acceleration force and other physical forces. This understanding will bring with it a logical awareness of other ongoing processes, and as a result, you do not even have to memorize incomprehensible material - you can memorize it as you progress. It is enough just to understand the essence.

Imagining everything in real life, you can quickly learn physical strength

To understand the electromagnetic effect, it will be enough to simply understand how the current flows through the conductor and what fields are formed in this case, how these fields interact with each other. Consider this with the simplest examples, and it will not be difficult for you to understand the principles of operation of an electric motor, the principles of burning an electric light bulb, etc.

The teacher will first of all care about how well you understand the studied material. And it is not so important whether you remember all the formulas by heart. And in the case of solving control, laboratory, tasks, practical work or buying a RGR, our specialists will always be able to provide you with essay help , whose strength lies in knowledge and many years of practical experience!
