Motor 1: P = 1000J/5s = 2000 W Motor 2: P = 1000J/10s = 1000 W We can state that motor 1 performs the work faster, then, it has more power When we do any work on an object, we transfer energy to it. Therefore, its energy increases. The system doing work develops power; this explains energy consumpti ...
