Sweet Spot

Interested in a better understanding of tennis physics? If so, try the home page of Australian physicist Rod Cross at Sydney University. A life-long tennis player, he explains what and where a racket's "dead spot" is and why balls bounce off the racket at the same speed whether you hold the handle firmly or loosely. Cross also uses tennis analogies to explain a baseball bat's "sweet spot."
