THE MIND-BENDING PHYSICS OF A TENNIS BALL\u2019S SPIN<\/h1>\n

TENNIS HAS BEEN\u00a0called the game of inches, of kings, of poets, of love, of errors, of endurance, of a lifetime. But those are mostly metaphors. Really, tennis is the game of spin.<\/p>\n

Watch Novak Djokovic send arcing yellow streaks from beyond his baseline to the bleeding edge of his opponent\u2019s backcourt. Watch Rafael Nadal\u2019s ground strokes cross a foot or more above the net, then drop like tactical bombs to the competition\u2019s ad corner. Watch Serena\u2019s opponents go crosseyed staring down her barrel-rolling 126 mph first serves. Go to any court in any city and you will find players at every level squatting, twisting, grunting\u2014trying to find that spin.<\/p>\n

It\u2019s fairly easy to figure out what spin does: It wins tennis matches. How it works\u2014or rather, how it\u2019s created\u2014on the other hand, is about as complicated a physics question you can set about solving without invoking subatomic particles. The variables include squishy balls, stiff racquets, taut strings, thrusting knees, twisting hips, swinging shoulders, and rotating elbows. But all those mechanics are made possible by a pair of equipment innovations.<\/p>\n
