Alpine skiiers face the forces of gravity, friction, wind and air resistance as they travel fast down hill on their skiis.

The kids learn how the rainbows works in detail.

Beakman explains why we keep our balance on a bike using a gyroscope. He then explains how a gyroscope works and performs a few demos to prove this.

Newton presents his findings on gravity to a group of scientists. Among the attendees are Sir Robert Hooke. During his explanation of the inverse-square law, Newton notices that Hooke appears to be stealing his work, so he abruptly ends his presentation.

The crew is trying to reach the shuttle that already landed on the asteroid. While traveling to it, the crew members come across a giant ravine in the asteroid and have no way to cross it. Since there is less gravity on the asteroid, they try to jump over the ravine. They successfully jump over it, and their trajectory leads them away from the asteroid, but they manage to turn the engines back on in time to return to the asteroid.
