Momentum and collisions

Grade 12 Physics Daniel Gockeritz PRACTICAL INVESTIGATION MOMENTUM AND COLLISIONS This report will investigate the theoretical velocity of a ball bearing gun. The methods and techniques used to derive the results will be shown along with the possible systematic and random errors caused by experimental limitations. Discussion: · Since the track is virtually frictionless and air resistance is neglected, the system is isolated; the net resultant force of the external forces equals zero. · The total linear momentum …

…body that was the combined mass and momentum of the previous bodies. The result was obtained by recognizing that the initial velocity/momentum of the ball bearing could be determined by utilizing the conservation of momentum law; that as long as the net resultant external forces equal zero, the momentum will be constant. From this exercise I learnt new method and techniques used in calculating errors and uncertainty. Bibliography Physics Investigation on Momentum and collisions
