1. The Cat-Traption


The cat's action, hitting the feather, initiates the entire chain reaction, and the potential energy stored in the tethered ball is transformed from form to form. In the last step of the chain, the cat eats its food, supplying its muscles with the energy it needs. If we reset all the devices, the cat can start the whole Cat-Traption reaction again.

There are a number of different forms of energy involved in the Cat-Traption. Make a list of all the different forms of energy you can find in the device. When you have your list (you may need to watch the video one more time, or watch the animated version on this site), check your version against the answers here.
