In physics energy is an indirectly observed physical quantity, besides it is one of the basic quantitative properties that describe the state of an object or physical system. Energy can be transformed into a variety of types, but the common unit of energy does not change. The forms of energy are: radiant energy, kinetic energy and various types of potential energy. It is a scalar value. In the SI system energy is expressed in joules, abbreviated as «J», », but in some spheres of science other units can be used: kilowatt time and calories.
