Jumpulse Tennis Double-Hitting

Posted on February 12, 2010 
Filed Under Tennis Doubles


A tennis double-hitting is caught on camera, when demonstrating super slow motiion video. The reproduction is in poor quality, but sufficient to show the double-hitting, which difficult to show because (1) It is hard for the eyes or the ears to detect and (2) Most players do not have the precise timing and the necessary sudden acceleration (jumpulse) to consistently perform double hitting in tennis under high-speed or normal playing conditions. Double-hitting is considered legal in tennis, if it is done within one smooth stroke. All the other sports, illegalizing double-hitting, could be violating physics. Jumpulse, a sudden change of force, is the solution of (robot) touch or collision without bounce.
