Mousetrap Car Physics Concepts
U3b-L7
If you are trying to build a long distance traveling or fast vehicle you will need to think carefully about the following concepts: Energy, Power Output, Inertia, rotational inertia, friction, torque, and pulling force.

Energy
Energy can be defined as the ability to do work. Work is the applying a force to an object, and actually moving that object. If the object is not moved, no work is done. The goal of the project relies on efficiently transferring the spring’s energy to the car’s wheels. The concepts involved in the transfer of this energy rely on an understanding of simple machines.

Energy
The trap acts as a lever to transfer the energy to the axle. The axle acts on the wheel as a second transfer of the energy. Finally, the energy is used to push the wheel against the floor, causing the car to move.

Energy
Any friction or resistance in the transfer of energy, leads to a decrease in the efficiency of the machine and decreased performance. Keep the use of simple machines in mind as you design the car, the correct use of these machines will increase your performance.
