3D Theory - Snooker - Cueing

If we hit the cue exactly in the centre of the ball (so that the cue, centre of the ball and direction of travel are all in the same line) then a linear impulse will be transferred to the ball.

This causes the ball to move, but not rotate, because there is no offset impulse which would cause the impulse equivalent to torque.
