What is energy?
In fact, everything that is in nature and everything that surrounds us is energy. We are people themselves clots of energy. However, let's all sort out in more detail.
What is energy? Energy is activity, action, power. And this is not all definitions of energy. Energy is a single measure of various forms of motion, a measure of the transition of the motion of matter from one form to another. The law of conservation of energy was invented by Aristotle. The law is as follows: energy is stored in time. But, provided that the physical system is closed. Energy, from the point of view of a fundamental system, is a quantity that is conserved during motion, associated with a single time - according to the Noether theorem. The dependence of energy and mass is expressed in the famous formula of Einstein. Einstein created the theory of relativity. The formula is as follows: E = m * c2, where E is the energy of the system, m is its mass, and c is the speed of light.
What kinds of energy exist? A huge number of species:
- kinetic
- gravitational
- mechanical
- electrical
- electromagnetic
- chemical
- nuclear
- thermal
- vacuum
- internal
- explosion energy
- potential.
Hypothetically, there is another kind of energy. It's called dark.
Energy is everywhere. If a person does not eat for a few days, he will not have energy and become weak. A lot of scientists are still unknown. All the greatest discoveries are waiting for us ahead.
