Things That Go "Bump" [Virtual Demonstration]

Is there more force when objects collide and stick to one another or when objects collide and bounce off each other?

This classic demonstration shows an important difference between elastic and inelastic collisions using "happy" and "sad" balls.

During remote teaching/distance learning (RT;DL), I produced this version of the demonstration. The instructional presentation link is included in the answer key; it's best if the instructor guides students through this. For Zoom presentations, Instant Reaction polls are included.
