  1. Roller Coasters By: Mr. Hunter

  2. What do you think engineers need to consider when designing a coaster?

  3. Engineers need to consider • Safety of riders • Height Restraints (Ex. Everest Expedition) • Law • Energy of car

  4. Why does the first hill have to be the highest point on a coaster? • Because the _____ energy must be the highest at the top of the first hill. • PE depends on the mass of the car and the height (gravity).

  5. What “drives” a roller coaster? http://www.learner.org/interactives/parkphysics/index.html

  6. 2. What are two types of wheels on a coaster car?

  7. 3. Explain the advantage of a wooden coaster. Explain the advantage of a steel coaster.

  8. 4. Describe the relationship between the height of the first hill and the speed of a coaster.

  9. 5. Why will a hill slightly higher than the first be a good design to provides ‘thrill’ for a rider?

  10. 6. Why are roller coaster loops not a perfect circle?

  11. 7. How does friction play a role in coaster design?

  12. 8. How does gravity play a role in coaster design?
