Third class. Because they are good for speed and longer movements and are arranged: FEL; Flucrum - Effort - Load. Other examples include brooms, fishing poles, and even your knees. On the mouse trap car the fulcrum is the bar that the spring is wound upon. The effort is the pressure on the snapper's lever arm that comes from the spring unwinding, and the load is at the end of the lever arm where the string is attached, the string that gets wound around the main axle and causes the wheels to turn when the spring is released.
A car door is a second class lever. The fulcrum is the hinges, the input force is the person opening the door, the output force is the way the car door swings, the bar is the door, and the load is the force put on the door.
The energy of the mouse trap racer is originally stored in the potential energy of the wound-up mouse trap's spring. The spring releases its energy and the potential energy is changed into kinetic energy of motion.
Conversion of energy tries to reduce energy loss in your mouse trap car. So there fourth, the friction. The wheels.
Drum sticks and rulers work great!

The best way to build a mouse trap car is to add four wheels to a peace of wood and add a mouse trap
You put your hand in a working mouse trap and start running;)
you can put elcteric wires under the mouse trap
It is better to use small trap cars as the larger ones can prevent no use to trapping a mouse the small traps are much quicker to get the mouse/rats.
Put a trap in your car and check the trap every once in a while.
It's the body of the car, yo.
inetia and friction
Wheeland axle definitely, lever I would say, and there are probably more I am missing.ur missing a pulley. that's also in there
you simply do what ever you want
