   ocr: Energy changes in the jetpack launcher On the moon, the jetpack launcher is asmall rocket that is used to fire the pinballs. Launching a ball sets up a complex series of energy changes. The fuel inside the launcher is astore of chemical energy. When you press the launcher button, the jetpack burns a litde of this fuel, producing lots ofl hot exhaust gases. The energy stored in the fuel has turned into heat energy: in the gases. The hot exhaust gases are made up of millions of tiny particles called molecules. These are constandy moving around and bouncing off one another. The hotter the gases a ...
