In a physics term, power is the rate at which work takes place or energy is transmitted. It can also be defined as the amount of energy needed or used to complete an activity over a period of time. The SI unit for power is the the Watt or "W". Other non SI units include horsepower "HP", calories per hour, "cal/hr", and foot pounds per minute "ft-lbs/min".
Equation The equation for power is where P is power, W is work and t is time. A second equation for power is P = E/t where E is energy and t is time. --Jaran Ellermeyer 13:15, 5 October 2007 (PDT)
