Power average (related to Work)


Power is the rate of doing work. It is equivalent to an amount of energy consumed per unit time. The same amount of work is done when carrying a load up a flight of stairs whether the person carrying it walks or runs, but more power is needed for running because the work is done in a shorter amount of time. If ΔW is the amount of work performed during a period of time of duration Δt, the average power over that period is given by the ratio ΔW/ Δt.
