Billiards Cut Shot Less Than 90 Degrees

August 23, 2003

Physicists will tell you that a cut shot in billiards cannot be made in which the cut angle is less than 90 degrees. The reason is simple. In order to cut the ball at less than a 90 degree angle, some component of force would have to be applied in the direction opposite the direction that the cue ball is travelling on impact. Another way to look at this is that the cue ball would have to contact the object ball at a point on the back of the ball – this cannot occur because other parts of the ball are in the way.
