Billiard Advanced - Ball Throw

Ball throw usually determine the movement of object ball from target line to the real ball path. Balls are thrown off-line by the friction between balls. If the cue ball hits an object ball at an angle, the friction between the balls throws the object ball path off the target line. Target line determined by a line through the centers of cue and object ball at time of contact and the actual ball path. The amount of ball throw depends on the angle of the shot, the English on the cue ball and the speed of the cue ball. See Spin Transfer for information on how English affects ball throw. More angles will mean more throw. Higher velocity reduces ball throw.
