Preparation: Velocity/Average/Explain It.

Average velocity is defined as the ratio of displacement and time elapsed. The applet on Page 2 displays these quantities and calculates the corresponding average velocity.

For details on how to use the applet see Help and ShowMe under Applet Help on the applet's Help menu. A Lesson on average velocity and average speed is available there as well. A useful listing of relevant notation and definitions is at the beginning of the Lesson.
