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?

11. B

12. A

13. D

14. The ball burnt off energy while rolling, it lost potential energy and couldn't go as high.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
