ME8.1 Air Track Collision
Some of the sleds have springy clips attached to each end for near elastic collisions, while others have magnetic bumpers for sticking for inelastic collisions. Place any assortment of these onto the air track and they will, given an initial push, bounce off of each other and the ends of the air track. If a moving puck hits a stationary puck of the same mass, all of its motion is transferred to the second. If two magnetic pucks moving with equal but opposite velocities collide and stick together, they will have no combined motion. Special computer experiment for air track collisions - using datastudio files on the demonstration laptop and PASCO photogate sensors, measure the before and after velocities of two particular masses (M and 2M) on the frictionless air track which collide elastically or inelastically.
