What is potential energy

What is potential energy

Scientists, mystics, just thinking people believe that all in the world is an energy. Atoms, molecules – everything moves, changes, will be transformed, becomes another and returns to an initial state. And all this thanks to that potential that it is put in each quantum from which the world is created.

Energy takes place from the Greek word designating "action". It is possible to call vigorous the person who moves, creates a certain work, can create, work. Also energy the cars created by people the live and dead nature have. But it in usual life. In addition, there is strict science physics which defined and designated many types of energy – electric, magnetic, atomic and so forth. However now it will be a question of potential energy which cannot be considered in a separation from kinetic.

Kinetic energy

This energy, according to representations of mechanics all bodies which interact with each other possess. And in this case it is about motion of bodies.

Potential energy

In physics this type of energy is created when there is an interaction of bodies or parts of one body, but at the same time there is no movement per se. In it the main difference from kinetic energy. For example, if to lift a stone above the ground and to hold in this situation, it will have potential energy which can pass into kinetic if to release a stone. Usually energy is connected with work. That is in this example the released stone can perform some work when falling. And the possible size of work will be equal to potential energy of a body with a certain height of h. The following formula is applied to calculation of this energy: A=Fs=Ft*h=mgh, or Ep =mgh, where: Ep - potential energy of a body, m - the body weight, h - body height over the Earth's surface, g - acceleration of gravity.

Two types of potential energy

At potential energy two views differ: 1. Energy at a relative positioning of bodies. The suspended stone has such energy. Interestingly, but potential energy also usual firewood or coal have. They contain not oxidized carbon which can be oxidized. If it is simpler to tell, the burned-down firewood potentially can heat water.2. Energy of elastic deformation. For an example it is possible to give an elastic plait, the compressed spring or the bones-muscle-linking system here. Potential and kinetic energy are interconnected. They can passes each other. For example, if to throw a stone up, at the movement at first it has kinetic energy. When it reaches a certain point, for a moment will stand and will receive potential energy, and then gravitation will pull it down and again there will be a kinetic energy.
