    Well what does a catapult do? Think about what a catapult basically is, brainstorm here.

    Tension is stored in a piece of rope or wood from a winch. When the tension is suddenly released it hurls the object. Check out http://science.howstuffworks.com
    They cover all the basic principles and will even sell you plans on how to build one if you like.

    Big ideas in a catapult(and, indeed, in alot of physics)

    1. Conservation of energy
    2. Conservation of angular momentum
