WORK, ENERGY AND POWER
... The LAW OF CONSERVATION OF ENERGY says that energy can neither be created nor destroyed but may be transferred from one object to another or from one form to another. POWER is the rate at which work is done, or energy is used. It is calculated as: Power = (Work done)/time or, Power = (Energy used)/t ...
