Science: The Great Race

The vehicle that I have designed and built was made out of a paper towel roll for the base, bottle caps for the wheels, metal hangers for the axil, and lastly, duct tape for extra support. First of all, I covered the wheels with smooth tape to reduce friction. I also added stones inside or "passengers" for extra mass. The extra mass would help the car expedite down the ramp. My car is an example of Newtons's Second Laws of Motion because my car uses the formula force = mass times acceleration. In this case, the force is created by the mass which is the stones and the acceleration, which is the push before it rolls down the ramp. Therefore, it describes the second law the best.
