A mouse trap car is a simple device that moves using the tension built up by a spring-loaded mousetrap. The mousetrap serves as the main and sole power source for the car. Several physical principles are applied when the mousetrap car is in motion, including energy, Newton's laws, inertia and friction. There are many different ways to create a racing car out of a mousetrap. Many different materials can also be used. However, the methods are all similar. In a way, the four wheels of the racing car were created for the first time. Any circular object with a hole in the center can be used. Two wheels should be smaller to fit in the front of the mousetrap and the other two wheels should be larger for the back of the mousetrap, which is opposite the snapper's arm. A rubber band was then tied around the circumference of each wheel. If the mousetrap has a rod that is used to secure it, the rod must be removed (tweezers can be used to do this). The mousetrap was then placed on the cardboard to serve as a base (frame) for the mousetrap. A piece of cardboard, half an inch (1/2") wider than the mousetrap on all sides, was cut with scissors. The mousetrap was then centered on the frame and secured with tape on all four sides, thus avoiding the spring in the middle of the trap and the trap arm. Four eye hooks were then screwed into each corner of the lower part of the frame. The hooks were aligned front to back and side to side with. a ruler Another method is to drill two shallow holes on each of the short ends of the mousetrap about ½ inch from each end Two thin skewers were then cut to a length about 4 cm longer than the width of the. axle rings. The skewers were cut so that...... middle of paper ......n. The mousetrap's energy is released quickly, the car will move faster, but will run out of energy sooner. If the mousetrap's energy is released slowly, the car will move more slowly, but will have energy over a longer distance. Many physical principles apply to a mousetrap racing car, although it is a simple device. A mouse trap car is very simple to make because it can be created using several different materials and methods. These two laws prove that the more massive the mouse trap car is, the more force it will take to move it. The mouse trap car works by transferring energy from the spring to the wheels of the car. Friction acts in several ways as the mousetrap car moves. All of these principles make the mousetrap race car work and should be considered when creating a mousetrap car..
