The Nine Ball Flight Laws
Knowing the nine ball flight laws can help us understand why we have that nasty hook or slice. This diagram shows the swing path/face angle and how they effect ball flight. All to common is the player with an outside in path creating a slice. They then swing even more outside in thinking this will hit the ball left, when in reallity they create even more side spin causing a bigger slice. Knowing the nine ball flight rules a slicer of the ball will know to work on creating a more in to out plane. Thus reducing side spin and creating a straighter shot.
