A shot in which the cue ball is struck above its equator with sufficient top spin to cause the cue ball to travel forward after it contacts an object ball . When a cue ball with follow on it contacts an object ball squarely (a center-to-center hit), the cue ball travels directly forward through the space previously occupied by the object ball (and can sometimes even be used to pocket a second ball). By contrast, on a cut shot , a cue ball with follow on it will first travel on the tangent line after striking the object ball , and then arc forward, widening the carom angle. See illustration at spin .
