No player can return this killer shot. Physics explains how it works

A study uncovers the physics of squash's "nick shot." This unbeatable shot happens when the ball hits the wall within a 1-inch range above the floor, compressing against it longer than rolling down. The ball's squishiness is crucial, storing and releasing energy horizontally. Though knowing the mechanics doesn't ensure improved play, players can boost their odds using a warm ball, powerful hit, and extended arm.
