The explanations of average velocity on the following pages use the applet on the left. For instructions on how to use the applet see Help and ShowMe under Applet Help on the applet's Help menu. An additional Lesson on average velocity is available under Applet Help.

You may want to experiment a bit with the applet before going on to Page 2.

Exercise. Drag the ball, observe the ball's displacement, and calculate the ball's average velocity using the value for the time elapsed from one of the two Data boxes.
