  6. When an object falls, what happens to its GPE?
  7. When an object falls at terminal speed what happens to its GPE?
  8. Derive a relationship between the height of an object before it falls and the maximum speed it can obtain by falling.
  9. What effect does doubling an objects mass have on its Kinetic Energy?
  10. What effect does doubling an objects speed have on its Kinetic Energy?
  11. What is does the Principle of Conservation of Energy tell us?
  12. For a roller coaster, does all the GPE become KE?
