In the second trial, the original prediction was that the elastic collision would knock over the brick and the inelastic collision would not. The prediction made was accurate to the results created. This happens due to the fact that an elastic collision there is no change in kinetic energy from before to after the collision. In the second trail, it was also predicted that the elastic collision would produce a greater impulse on the brick, due to what had already been learned from the second trail, and this assumption was accurate. For the third and final trail, it was predicted that both the elastic and inelastic collisions would produce the same amount of momentum. This prediction was not accurate with the final results. The elastic collision
