Homework Help: Potential Energy in to Kinetic Experiment

  1. Dec 4, 2007 #1
    Hi, I just need a little help brainstorming some ideas for my upcoming experiment on stored potential energy converted to kinetic energy.

    Basically, you build a car and some way it has to move to a certain distance.

    The rule is, the car has to move exactly 2m to a dot and we're not allowed to have an external force on the car.

    My ideas so far: balloon on the back of my car, or a mousetrap and some how spin the wheel

    Any help here will be welcome and also if you guys could... please add some procedure of a way to accurately find out how to get to 2m thnx a bunch

    A spring. When you roll the car backwards, the spring winds up. When you let go of it, it unwinds and propels the car forward.
