On the bottom of the interactive next to the Construction Tools are a set of displays that show you Total Energy, Potential Energy and Kinetic Energy. As your car rolls along the track, watch how these are exchanged. When is the kinetic energy largest? When is potential energy largest? Are they ever equal? There is also a speedometer that allows you to follow the changes in velocity. Roller coasters are most fun when you feel accelerations: you experience as a force throwing you back and forth. Accelerations are changes in velocity. Can you build a roller coaster in which the rider feels a lot of accelerations? |
