This experiment was performed by six total trials with the bumper engaged (elastic collision) three trials runs and the Velcro engaged (with the bumper pulled in) for three runs of inelastic collisions. The carts had added weights, to determine the change in kinetic energy loss or gained before and after the collisions. The uncertainty in initial momentum calculated was 1.9X10^3 kg*m/s and the uncertainly in final momentum was calculated at 6.7X10^4 kg*m/s. Most of our percent differences in initial to final kinetic energy were calculated as very high values, mostly higher than 100%. Therefore, neither linear momentum or kinetic energy was really conserved within the elastic or inelastic collisions. Possible sources of error include a small frictional force and air the elastic or inelastic collisions....
