Swerve question

[Patrick Johnson]

Not if you're comparing swerve with follow to swerve from draw. If the stick is elevated to the same angle, the swerve angle will be larger with draw (by the Coriolis masse principle) but the curve will be over a much wider extent than with follow. The ball will swerve until it is rolling smoothly on the cloth and that happens sooner with follow. The result is that the path of the ball with follow and the ball with draw will cross. For short distances the follow appears to have more swerve while for long distances the draw appears to have more swerve.

Do the lines cross within the range of most shots?

I agree with Bob & I think when the lines cross is relative to speed first & distance for a given speed.

The distance of crossing will depend on the speed of the shot. I think follow shots may do all of their curving within a few inches on a two-table-length shot. A draw shot, which may have two or three times as much angle change as a similar follow shot, will be curving for four or five diamonds, depending on the cloth. I think that will give a crossing point with the follow shot very roughly where the drawn ball changes to smooth follow. Lots of variables can change the result such as the use of more elevation on draw shots. I think that Virtual Pool will model this accurately if you want to try a computer experiment

Do you think a cue ball will swerve more with (1) High right , (2) Low right or (3) Center right? Why?

It depends entirely on attack angle.... Upstroke.. Level stroke... Downstroke will impact swerve more than where the cueball is struck......
