Phil explains and illustrates Newton's first law of motion and angular momentum using a 20 kg weight. In the experiment, they are having trouble spinning the weight fast enough. They eventually spin it fast enough that it doesn't topple over immediately.

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

Bill Nye show us how a circuit works by comparing electrons to water.

Mr. Seaver begins teaching the class a lesson on gravity out of the textbook. He is especially confused by the book's claim that a coin and a feather will fall at exactly the same speed. After Luke challenges him to prove it, he tests the claim.
