The ball must have sufficient height, time of flight and distance. If the angle is 45 or less there will be less vertical height on the ball and too much horizontal distance causing the ball to travel over the net. The angle is more than about 55 degrees the ball will just travel straight up. There may be enough vertical on the height of the ball but it won’t travel to the setter. The higher angle of projection will have less horizontal distance but more time of the ball in flight.The angle between the forearm and the ball has to be just above 45 degrees. A pass around 50 degrees will have the correct vertical height of the ball, horizontal distance and time of flight. In biomechanical terminology angular motion is defined as a rotation of a whole body segment implemented around an axis of rotation. In the execution phase the hips must be turned towards to the target. The body segment used in the angular motion is hip and the axis of rotation would also be in the hip area. The angular distance for the rotation of hip would not be a large amount. Depending on where you are positioned the angular distance would change. Newton’s Third Law states: For every action there is an equal and opposite reaction.In a forearm pass the ball hits the hands just as hard as you hit the ball. When a hard float serve hit your forearms it creates an equal and opposite reaction in the opposite direction. Also, to make the ball go where you want it to go your must hit it in the proper spot with the proper force. In the completion stage if you swing your arms to
