In this applet, a single ball is dropped and tracked. In effect, a movie. You can view frame by frame, also, and slow down the motion by choosing a smaller time interval.
In this applet, all previous positions of the ball are displayed as it drops. In addition, a ruler is available. In effect, a fancy stroboscope.
In this applet, the position of the dropping ball is displayed next to a graph of position against time.
