The problem was to determine the energy efficiency of three cart collisions. Our group had to see if the energy efficiency changed when the mass of the individual carts changed, but the net mass stayed the same. In the experiment, we have a cart hitting a stationary cart and, after the collision, moving together. We changed the masses by first having the moving cart lighter than the stationary cart. We then had both of them having equal mass. Then we had the stationary cart more massive than the mobile cart. This resulted in three videos. We captured the experiment using VideoRecorder. We then analyzed each video with VideoTool. Theoretical Calculation: Our group predicted that damage done in a collision has to do with the individual mass of the cart, not the total mass of both carts.
