Energy from Movement
Poor old Bristlebones! His pirate ship has sailed away, and he’s stranded on a tiny island. He can think of only two ways to get help. He can fly a kite and hope somebody sees it. Or he can put a message in a bottle and let it float away in the ocean and hope somebody finds it.
Each of old Bristlebones’ ideas depends on a kind of energy – the movement of wind to lift a kite and the movement of water to carry a bottle. Moving things like wind and water have energy that can be used to give something else a push or a pull.
Anything that is moving has energy, even the coconuts on Bristlebones’ tree. While the coconuts are falling, they can give quite a push to anything they hit, including Bristlebones’ head!
