Beakman's World: Stopping Forces
00:18:08 - 00:19:18
Science → Physics → Inertia
Beakman puts a dummy doll on a skateboard and rolls it down a ramp. It can't stop until it hits something. The skateboard hits a wall and the dummy doll flies until it hits the floor. Both objects needed to be stopped by interacting with a non moving object or force.
