Energy , in physics , the capacity for doing work. It may exist in potential , kinetic , thermal , electrical, chemical , nuclear , or other various forms. There are, moreover, heat and work—i. After it has been transferred, energy is always designated according to its nature. Hence, heat transferred may become thermal energy , while work done may manifest itself in the form of mechanical energy.

In physics , energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat , the object. The SI unit of energy is the joule , which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton. Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field gravitational , electric or magnetic , the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns , the radiant energy carried by light, and the thermal energy due to an object's temperature. Mass and energy are closely related. Due to mass—energy equivalence , any object that has mass when stationary called rest mass also has an equivalent amount of energy whose form is called rest energy , and any additional energy of any form acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy.
