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.
Adam Conover explains how the electoral college system is unfair by favoring voters in states with smaller populations. He also contends that swing states have significantly more power than any other state and that 80% of votes have no impact on the outcome of presidential elections. He clarifies that the public votes for its state's electors, not the president, while the electors cast the vote for the president and vice president.
Beakman explains how glider planes use gravity to fly by taking advantage of potential and kinetic energy. Using a swing, Beakman explains what potential and kinetic energy are. He also explains how the sun creates thermal heat which lifts the planes as well.
