Using the data that was found, the kinetic energy for before and after the collision was calculated for each experiment by using the equation KE = 1/2mv2. The velocities for before and after the collision were different but the mass used, 0.6735 kg, was the same. The impulse was found by using the equation F (Δt). Also, the change in momentum was found by using the equation m (Δv). The numbers that were used in these equations were found while carrying out each experiment. The percent difference was calculated by using the impulse and change in momentum values. When looking at the shape of the force vs. time graph, it was seen that a small force acting for a greater period of time could deliver the same impulse as a large force acting for
