When work is done using an energy source, say a battery, energy is consumed and the battery is able to do work till its chemical energy is consumed.
Everytime an object falls down work is done by gravity ? Suppose everybody in the universe starts dropping objects into canyons, valleys and the oceans on earth, then why isn't it possible to exhaust gravitational energy.
