The bobsled needs to be accelerated first through a 50 meter push and then the team need to find a way to maintain their velocity to be the fastest.

Double D and Ed attempt to perform Galileo's experiment on the effects of gravity on objects of different masses using a bowling ball and a marble. Before beginning, Double D states the assumption that, when dropped in unison, the heavier object will accelerate first. Then, he clarifies and states that objects dropped at the same time, regardless of weight, will hit the floor at the same time.

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.

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.
