If a metal sphere that weights 1.006 kg is dropped from 2.5 meters, what is it's kinetic energy when it hits the ground?
Is this kinetic energy the same value as mechanical energy?
If this kinetic energy was converted in electrical energy by a 1000 watt electric generator that was 95% efficient, how much mechanical energy (in joules) is required? In other words, does a 1000 watt generator require 1000 joules of mechanical energy?
