Four Motions

The applet window is divided into four panels, labeled (a) - (d).

Four different motions are simulated in these panels:

• (a) circular motion with constant speed
• (b) parabolic motion with non-constant speed
• (c) straight-line motion with non-constant speed
• (d) straight-line motion with constant speed

To start one of the motions, one clicks inside the relevant panel. To stop the motion and reset, click again inside the panel. To start the motion once more, click again inside the panel.
