A GRAPH IS NOT A PICTURE!

Click "(re)start". The applet shows:
  1. the picture of a red ball moving vertically in the x-y plane, and a graph illustrating how the vertical position of the ball changes with time.
  2. the picture of a blue ball moving horisontally in the x-y plane, and a graph illustrating how the horisontal position of the ball changes with time.
Spend some time understanding the difference between a picture of the motion in the x-y plane, and a graph of the motion against time.
