Help - Four Motions

The applet simulates four motions of a particle. Three of these involve an interaction of the particle with one or several other objects, while in one motion the particle is not interacting with anything.

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 play/pause any of the motions, click the START/PAUSE Play / Pause toggle button of the relevant panel.

To stop the motion and reset, click the RESET Reset button for that panel. You can run more than one motion at once.
