ABSTRACT
The same is true of tennis, .... Did I get your attention? Even a McEnroe-esque screaming tantrum on the tennis court is unlikely to have physical contact, so why would I claim that tennis is a sport of collisions? Here’s why: every point starts with a collision between racket and ball, followed by a collision between ball and ground, and so on. The motion of the ball, and therefore the outcome of each point, is determined by these collisions.
