How does a Mousetrap Powered Car Work?

1 Answer

A standard mousetrap powered car has a piece of string attached to the jaw of the mousetrap. The other end of the string is coiled around the rear axle. The mousetrap powered car works by changing the kinetic energy (of a loaded mousetrap) into kinetic energy (when the trap springs). The jaw snapping shut pulls the string, which makes the axles turn, which spins the tires-propelling the car forward. You can find more information at http://www.mousetrapcar.com.au/... more
