ABSTRACT
Start simply with this bouncing ball exercise. At the peak of its bounce, a standard rubber ball will retain a perfectly spherical shape. However, after it descends and hits the ground, it will deform into a flatter, “squash” shape. Yet when it’s either ascending or descending, the ball will tend to adopt a longer, narrower “stretch” position. So, take a decorative ball and on the next blank page sketch all 3 modes of it bouncing: perfectly spherical, squashed, and stretched. Ensure that the overall size and volume within the ball are consistent from drawing to drawing. If you have space on the page, repeat this exercise more than once. (Take no more than 2 minutes to complete each drawing.)
