A roller coaster is very similar to a pendulum in terms of kinetic and potential energy. Use the illustration below to answer the questions.

1. __________ Which letter in the diagram represents the place where the cars on the roller

coaster would have the most potential energy?

2. __________ Which letter represents the place where the cars would have the most kinetic

energy?

3. __________ Which letter represents the place where the cars would have the least kinetic

energy?

4. __________ Which letter represents the place where the energy would be changing from

kinetic to potential energy?

5. __________ Which letter represents the place where the energy would be changing from potential to kinetic energy?

6. __________ Where in the diagram would the cars be moving with the greatest speed?

7. Why do you think that the first hill on the roller coaster must be the tallest? (explain your answer in terms of kinetic and potential energy.
