For our lab, we hooked up our robot car to a set on weights attached to a pulley. Three different aspects were tested to see how differnent factors would play off of each otherThrough three different trials of three for each test. First, more weight was added to increase the mass. It was found out that the more the mass was increased, the less the acceleration became. Next, it was found out that if the acceleration was increased then the power would be as well. Finally, it was found out that the smaller the mass was, the less the battery discharge would be. All three played off of each other providing a clear picture as to how the process worked.
