Energy is stored in the spring to start. (PE)

As it starts to release, the energy travels down the string and into the axel. (KE)

The car starts to move, the mousetrap spring loses energy and the wheels start to roll. (KE)

The friction between the wheels and the ground slows the car down. (turns into heat -- KE)

The car loses energy and comes to a stop. (PE)
