Beakman's World: Inertia Keeps us Grounded
Through a cartoon movie, Beakman explains why your stomach feels weird on a roller coaster and why the biggest hill is the first one. He hangs a bowling ball from the ceiling with a cable and then swings the ball to squish a watermelon (energy in and energy out). He then puts himself where the watermelon was and shows that the ball can't swing any farther than the point at which he lets go. Beakman goes on to explain that centripetal force prevents us from falling out of the roller coaster and demonstrates it. He uses a tray containing a glass of milk and a cupcake and quickly spins it around to show that nothing falls off. He then explains why inertia keeps us from falling to the ground and brings all of the concepts together. -
Beakman's World: Tightropes and Inertia
Beakman uses someone walking on a tightrope with a long pole to explain rotational inertia and shows a demo of walking with and without a long pole. -
Beakman's World: Egg Experiment
Beakman sings a song about Isaac Newton and inertia and pretends to be Newton to explain his Laws of Motion. To demonstrate the Laws of Motion, Beakman does an experiment where he has eggs on cardboard tubes resting on a piece of cardboard over cups. He asks what would happen if the broom moves the cardboard. He hits the cardboard only, the tubes and cardboard are moved, and gravity pulls the eggs down into the cups. -
NBC News Learn: The Science of Arial Skiing
Arial skiing requires skiiers to perform jumps and twists in the air on their skiis. Rotating objects have angular momentum and moment of inertia. The skiiers must understand the physics of how they move to perform better -

04:25
Lester and Phoebe have a contest to see who can rotate an apparatus the fastest. The two apparatuses weigh exactly the same, but Phoebe wins because the weights on hers are closer to the middle. This demonstration explains how figure skaters can spin faster when they pull their arms and legs inward. -
