Scientists, mystics, just thinking people believe that everything in the world is energy. Atoms, molecules - everything moves, changes, transforms, becomes different, and returns to its original state.
And all this is due to the potential that lies in every quantum, from which the world is created.
Energy comes from the Greek word,Denoting "action". You can call energetic person who moves, creates a certain work, can create, act. Also, the machines created by people, living and dead nature possess energy. But this is in ordinary life. In addition, there is a rigorous science of physics that defined and designated many types of energy - electrical, magnetic, atomic, etc. However, now we are talking about potential energy that can not be considered in isolation from kinetic energy.
This energy, according to the ideas of mechanics, is possessed by all the bodies that interact with each other. And in this case we are talking about the motion of bodies.
In physics, this kind of energy is created whenThere is an interaction of bodies or parts of one body, but there is no movement as such. This is the main difference from kinetic energy. For example, if you lift a stone above the ground and hold it in this position, it will have potential energy that can go to kinetic if the stone is let go.
Energy is usually associated with work. That is, in this example, the released stone can do some work in the fall. And the possible amount of work will be equal to the potential energy of the body at a certain height h. To calculate this energy, the following formula applies:
A = Fs = Fт * h = mgh, or Еп = mgh, where:
En is the potential energy of the body,
M is the mass of the body,
H is the height of the body above the ground,
G - acceleration of gravity.
Two types of potential energy
There are two types of potential energy:
1. Energy in the mutual arrangement of bodies. This energy has a suspended stone. Interestingly, but the potential energy and have the usual wood or coal. They contain non-oxidized carbon, which can oxidize. If to tell more simply, the burned down fire wood potentially can heat water.
2. Energy of elastic deformation. For example, here you can give an elastic tourniquet, a compressed spring or a system of "bone-muscle-bunch".
Potential and kinetic energyAre interrelated. They can pass into each other. For example, if you throw a rock up, when moving first, it has kinetic energy. When it reaches a certain point, it will momentarily freeze and receive potential energy, and then gravity will pull it down and again the kinetic energy will arise.
