Your at a carnival and your amazed at all the rides especially the ferris wheel. Did you ever think of potential energy in the ferris wheel. Well first of all potential energy is stored energy. So the ferris wheel is not started yet, and your looking at the amazing height. People are getting in the first cart and the ferris wheel just started. All the energy before that was stored energy witch is potential energy. The ferris wheel looks fun so you get in line. Your watching it move it looks more fun as it startes to move a little faster. Moving energy is kinetic energy. Its finally your turn your so excited. Then it started to move, now it starts to move your scarred. The cart starts to shake now your even more scarred. Really your scarred of kinetic energy witch again is moving energy. This is also a tramsformation between potential and kinetic energy in a mechanical systems.
