Can you hit a pool ball 90 degrees?

What is the 90° rule? The 90° rule states that for a stun shot, where the CB has no top or bottom spin at impact with the OB, the CB and OB separate at 90°, regardless of the cut angle (except for a straight-in shot, in which case the CB stops in place).

What angle should I hit my pool ball?

This "90-degree rule" is a result of physics—because momentum is conserved, after the collision, the cue ball must move in a direction that is perpendicular to the motion of the other ball. Hitting the cue ball below or above its center will cause it to spin, which affects the angle at which it will rebound.

What is the 2 hit rule in pool?

"A double hit is an illegal shot involving the tip of the cue stick coming into contact with the cue ball twice during the execution of a single shot. This foul may occur through double clutching the cue ball, or in situations where the cue ball is nearly frozen to the object ball or rail.
