Energy

Energy:

Measure of the ability of a body or system to do work or produce a change. No activity is possible without energy and its total amount in the universe is fixed. In other words, it cannot be created or destroyed but can only be changed from one type to another. The two basic types of energy are; Potential: energy associated with the nature, position, or state (such as chemical energy, electrical energy, nuclear energy). Kinetic: energy associated with motion (such as a moving car or a spinning wheel).
