The word “energy” is derived from the Greek word “energeia,” which means “activity” or “operation.” The SI unit of energy is the joule (J), which is defined as the work done or energy expended when a force of one newton (N) is applied over a distance of one meter (m).
In physics, energy is the property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be neither created nor destroyed, but only converted from one form to another.
