power is the ability to get someone to do something he or she would not otherwise do” Work-Energy PrincipleThe change in the kinetic energy of an object is equal to the net work done on the object.This fact is referred to as the Work-Energy Principle and is often a very useful tool in mechanics problem solving. It is derivable from conservation of energy and the application of the relationships for work and energy‚ so it is not independent of the conservation laws. It is in fact a specific application

car powered by a mousetrap. This car works when one end of a string is tied to the arm on the mousetrap and the other end is wound around an axis. By winding the string around the axle the mousetrap’s spring is stretched providing stored energy. As the mousetrap is released it pulls the string off of the axle causing the wheels to turn and making the car move. PROJECT The objective of this project is to design a MOUSETRAP CAR for maximum DISTANCE and to demonstrate an understanding of

ending up getting pop caps from Ms. Chambers. Since our idea was to use highlighters and the wire‚ once we hammered a hold through each of the caps‚ we couldn’t figure out how to make them turn because we did not have a good axle. We tried to use just a straw for the axle and that did not work. We then tried to compact the

meters in the quickest amount of time. A mousetrap car works when one end of a string is tied to the arm of the mousetrap. The other end of the string would then be tied around the axle‚ this would stretch the mousetraps string which would provide stored energy. Once the mousetrap is released it will pull the string off the axle which will cause the wheels to turn and result in the car moving. There are many physics concepts that apply to the mousetrap car such as Newton’s laws. Newton’s first law known
