Animation 1 | Animation 2 | Animation 3 | Animation 4 | Animation 5

Please wait for the animation to completely load.

Five animations depict a ball moving from left to right through the starting and finishing gates. Instead of showing the motion of the ball, a graph is shown of the relative probability (therefore it is not necessarily normalized) of finding the ball near a given position vs. that position. Only when the ball is between x = 0 m and x = 10 m is this information sent to the graph.  Restart.  View the animations and then:

1. Rank the animations by the acceleration of the balls. Ties in ( ) please.
2. Qualitatively describe the potential energy function in each animation.
