Mousetrap Car Final Paper
Design Description
Our car had four CD wheels that were attached to the axle of the car with CD spacers. We put balloons over the wheels for traction. The body of the car was two pieces of wood that was attached by the mousetrap car sitting on top of both of the pieces of wood. The lever arm is attached to the mousetrap with a piece of string to turn the axle; therefore, turning the wheels. Then the body of the car is held in place by four CD spacers on the outside of the body of the car. How do Newton’s three laws apply?

Newton’s first law of motion, every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it, relates to mouse trap cars because the mouse trap car will not move unless it is propelled by the mousetrap. Newton’s third law of motion states that the acceleration of an object is directly proportional to the force and inversely proportional to its mass. This applies to the mousetrap car because the force of the mousetrap is greater than that of the friction or air resistance. This allows the mousetrap car to accelerate. Newton’s third law of motion states that for every action there is an opposite and equal reaction. This applies to my mousetrap car because the force of the air resistance is the same as the force of the mousetrap car, but the direction of the force is backward because the car is moving forward. How does friction affect the mousetrap car?

Friction played a big part in our mousetrap car as does it in any other mousetrap car. The surface friction caused our car to stop. Our car had less friction than other cars because we tried to make it as light as possible because if you have more weight, there will be more friction than that of something that is lighter. Problems

My group and I had very little problems when building our mousetrap car. When we first finished building our car we wanted to tighten the spring so we did that. Then our mouse trap...
