Oooooh so exciting. Volleyball is a foreign world for me. All I know is that the net can make a pulse when you hit it. However, I've just learned stuff. A lot of kinetic and potential energy in the players, and as for technical stuff with the ball—seems like a bunch of acceleration, momentum and timing. Yaa-hoo for physics and Eike<3 By the way, it seems my picture is a dog... I wonder who did this...
