Answer 2

Energy is a commonly used term in everyday life. We talk of energy in terms of physical energy of an individual by the amount of work a body can do.

Thus energy is the capacity to do work. This energy can be due to its state of motion, position or configuration. An object, when raised to a certain height or made to move, posseses a certain amount of energy. Energy and work being the same nature are expressed by the same units.

SI unit = joule(J)

CGS unit = erg
