I've found out a little bit about cue ball movement from snookertips.info...
- The cue ball's movement is determined by its forward rotation (spin) on impact.
- With no spin on impact (a stun shot), it will deflect 90 degrees in the opposite direction to the object ball.
- Forward spin (follow) and backward spin (draw) on the cue ball affects the amount of deviation from 90 degrees. So, more follow means a sharper curve upwards, and more draw, a sharper curve downwards.
- It is also affected by the angle at which the cue ball hits the object ball; thicker contact means that the follow and draw have a bigger effect, both on position and speed.
This video shows an impressive curve of the cue ball when shooting with follow.
An impressive 28 second spin can be seen 1 minute and 3 seconds into this video.
And you just HAVE to check this out!
