Reference: AQA
The watt tells you how quickly energy is transferred or work is done, so a higher power means more energy transferred each second.
Energy transferred per second, so the faster motor transferring the same energy in less time has the greater power.
Power is the rate at which energy is transferred or work is done, measured in watts where 1 W = 1 J/s.
How quickly energy is transferred, measured in watts (W), where one watt equals one joule per second.
The meaning of a calculated power value, for example 920 W means 920 J transferred each second.
