This graph shows a ball rolling from A to G. The ball starts at point A and rolls to point G.
11. At what letter does the ball have the greatest kinetic energy? __________
12. Which letter shows the ball when it has the maximum potential energy? __________
13. Which letter shows the ball when it has the least potential energy? ___________
14. Why is point G slightly lower than point A? In other words, why couldn’t the ball go back to the same
height at which it started?
