Stored energy
Energy can wait, stored, until it is used. Food, fuel and batteries store energy in the substances they are made of. A stretched elastic band, a drawn bow or a wound spring store it in their shape, and a thing lifted up high stores it in its height: the higher it is, the more energy it has to give when it comes down. Water behind a dam and a child at the top of a slide both hold energy this way.
