Answer #1

Power is the rate of performing work. It is a measure of how much energy is created in each second that passes, the size of the force applied and the velocity at which it is applied.

Power = {(Force × Distance) ÷ Time}

represents the product of strength and speed of movement expressed in Watts. Where Force is measured in Newtons (1kg=10N), the Distance in metres and Time in seconds.
