pool sidespin--squirt & swerve revisited

I don't think you addressed how speed affects squirt, but great video nonetheless.

cool video.

Very well done - I've never seen a better illustration of these points. May want to slow down on the pivot point explanation, as it seems to have confused some of the viewers who think it has to do with rotating the cue around it during the shot...

The last diagrams describes a problem that I have been trying to understand, which is, when using side spin, are you supposed to pivot (as the diagram suggests) from your straight aimed cue position, or, instead, simply move the cue as a whole to one side but keeping it parallel to its original position? Wouldn't keeping it parallel reduce swerve even more than simply pivoting? Thanks.

You must keep the ball parallel when using side. Any pivoting of your aim is changing the direction of force, in effect changing your aim. The mass wants to move away from the force at 180 degrees. To keep it simple, keep the direction of force the same as if you were hitting center ball.

Due all cue modifications have to be internal?.........If a person was allowed to add ringed weights to the shaft you could tune the cue.......Just curious.

This is useless,all depends on the cue and feeling,there are some specific cues when you hit the sidespin the cueball goes straight as rope

Excellent explanation, very thorough and helpful. I just have one quick question about the pivot point mentioned, and if its representative of the hand? Thanks
