Hitting the ball below its center creates backspin, causing the cue ball to roll backward after impact [23, 10].

Advanced players fear squirt—the deviation of the cue ball’s initial path when using side spin. When you strike off-center, the cue tip applies an impulse not aligned with the center of mass, causing the ball to "squirt" opposite the spin direction. Advanced players fear squirt—the deviation of the cue

In reality, collisions are not perfectly elastic. The coefficient of restitution ($e$) measures the "bounciness" of the collision. For high-quality phenolic resin billiard balls, $e \approx 0.95$ to $0.98$. This slight loss of energy results in the angle between the two balls being slightly less than 90 degrees, a phenomenon known as the "inelastic correction."
