What is potential energy?
C XIX century solved the problem for a person, what is potential energy or potential. Scottish physicist-engineer William Renkin coined this term, implying a physical quantity that describes the capabilities of bodies or material points, objects, to perform certain actions within other active forces. It can be said that this particular image is a characteristic of interactions between a body and a field or several bodies within the framework of a scientific approach to the study of this phenomenon. After all, joint activities may be different and with different potential. This is a kind of body energy that arises because of its location in a specific place at a specific height in the gravitational field of the Earth.
The pendulum, as a oscillating system or a compressed spring, as energy in reserve - these are the most common examples for familiarizing yourself with the concept of potential energy. Any physical object located on the shelf will have it in the ratio mgh, while m is the weight of the object,g is the acceleration during the free fall, and h is the height of the position of the mass of a body or object, from a selected arbitrarily zero exponent. Measured in joules. If a fall occurs, the energy is reincarnated into kinetic. The kinetic energy is also determined for one body, while the main indicator is speed. At the same time, the determination of the potential requires two bodies or a field interconnected with the object. The physical meaning and the main significance lies in the change, and not in the very meaning of the potential energy.
