Gracie PhillipsP212/3/18Mousetrap Car Analysis1)The mousetrap car runs only by the force of the mousetrap snapping closed. In order to activate the force and propel the car, the mousetrap is attached to the body of the car and a string is tied around the lever of the mousetrap, which is how the mousetrap snaps. The string is then wound around the axle opposite the resting direction of the lever until the lever is fully cocked backwards and the string is taught. Once the lever is released, the lever goes forward due to the tension of the spring force and pulls the string with it, in turn spinning the axle and wheels and sending the car forward. 2)Potential energy is energy that is present yet inactive in an object for the time being, while kinetic energy is energy exerted by a force and is in action. Potential energy is found in the car when the lever is cocked back and set to release but has not been released yet. The kinetic energy, consequently, is found once the lever is released and moves forward as a result of the spring force. The potential energy changes to kinetic at the point of release. 3)One simple machine utilized in the mousetrap car was the wheel and axle system. In a nutshell, the wheel is attached to the axle and by spinning the axle the wheels are spun and the system moves forward. On my car specifically, but in reality most cars, there were four wheels and two axles, each of which was located on the ends of the mousetrap car. My car though was four wheel drive, meaning that as the mousetrap car is propelled by a string wound around the back axle, my car had one string wrapped around the back and one wrapped around the front. Thus, at the release of the mousetrap, both strings spun both axles and all four wheels spun forward.
