Racket/ball impact at 45 degree angle in super-slow
Shows how spin is generated when a non-spinning ball hits an angled racket. Sort of cool, I think, to see it in super slow motion, although very brief:
Another video shows what happens when a tennis ball hits the racket at 1000 km/h. The racket starts to break even before it's hit by the ball (because of the air pressure from the air pressure cannon)! Pretty useless video, but I guess they were just having fun at the lab. http://www.youtube.com/watch?v=EtbZaqgUlv8
