Watch this roller coaster and think about what is happening to the energy in it:
- Does the total amount of energy change as the coaster runs?
- Identify when the kinetic energy the greatest amount.
- Pinpoint when potential energy is at the maximum amount.
- Describe what happens to the energy as the coaster comes to the end of the track.
- Is the relationship between potential & kinetic energy inverse (when one goes up, the other goes down) or direct (when one goes up, the other goes up / when one goes down, the other goes down)?
- Watch it again and pay close attention to the calculations for Potential and Kinetic Energy. What are the equations for both?
- What observations can you make about who these numbers are changing throughout the coaster's ride.
