Usain Bolt holds the world record for being the fastest man alive. Runners require an incredible amount of strength because the stronger their muscles are the more strength they have to exert and push off the ground as they run.

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.

Phil explains to Mike how the block and tackle system that him and Dr. C have made to haul Phil out will have the power to do so.

Luke tries to use the Force to recover a sunken ship. He is unable to fully recover it because of its weight. This clip shows that force is proportional to the mass of an object.

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.
