Activity: Collisions

IB Physics: Activity: Collisions

If you can"t remember how to use video analysis here is a video.A collision in which both momentum and KE are conserved.Remember momentum is only conserved if the balls are isolated, this is a problem in the lab (as you have probably noticed) since the balls interact with the track. To eliminate the track we need to switch off gravity or remove friction and we can only do that in a simulation.
