it builds momentum like when you see them follow through they carry on because of all the force. (depends if you are a fast bowler) remember f=ma (force x mass=acceleration)
(the last guy did wrong equation)

It is a simple matter of physics. By running up before they throw said object, they create a certain momentum behind the object. By stopping suddenly, they transfer the motion to the object and throw it harder/farther. You see the same thing in baseball, football and basketball. The equation that explains it is:
Force X Mass = Acceleration
