Squash and Stretch

This online activity has you order multiple images of a bouncing ball to show how, in animation, an object appears to lengthen as it falls, flatten as it hits the ground, and lengthen as it bounces up. This technique is used to produce the exaggerated look of an animated cartoon, but follows the rules of physics in that the object elongates along its axis of acceleration (stretch) and contracts when it meets resistance (squash). If images are out of place, they can be moved, rather than starting all over.
