You spin me right round Baby right round baby right round

http://coach-al.smugmug.com/gallery/7639568_pPyVY#493866658_29jz4-M-LB here is a picture of one of our volleyball games. I couldnt get the picture because coach AL needs to make money by selling these pictures anyways. In the picture i tos the ball up in the air to serve it. Analyzing the picture i noticed that when i toss the ball i put some spin on it giving the ball rotational intertia. Newtons second law clearly states that an object in motion stays in motion so if i were to ignore outside forces and wind resistance the ball would continually be spinning. As my body is jumping i twist my shoulders to increase the torque so i can hit the ball with a greater force. Isnt physics neato i think so.
