Quick question about Cut Induced Throw

A

Hello,

when you cut a ball (for example 45 degrees) , does the object ball goes straight with an initial angle less than 90°, or does it start on the tangent line THEN does a slight curve?
I am asking because every time I pot a ball while compensating for throw, I first think I missed it and then the OB finally goes in. Just tell me if my eyes are wrong.

Thanks

Any time the separation deviates from the line of centers, something somewhere, curves.

And if Fat Fred is standing on the right side of the table, he will help the ball curve around an obstruction. Gravity rules!

The question is whether the curve is significant on any normal shot. It is not. The OP should worry about it no more than he should worry about where Fat Fred is standing. Unless the floor really needs bracing.

Is there still spin on the cue ball as it strikes it's contact point?
If so is it inside or outside spin?
Or is the spin gone and the cb is rolling naturally?

Try this experiment: put an object ball 3 feet off an end rail with the cue ball 2 feet from the object ball. Position the balls so that the object ball is a slight cut diagonally into a corner pocket on the far end of the table, so almost straight in. Hit center ball on the cue ball and hit 10 or so shots with between slow to medium speed, so that you feel comfortable where the aim point is to make the object ball. Now, with the same aim point hit backspin on the cue ball to back up the cue ball to at least the end rail and watch where the object ball goes. Do the same thing hitting the top of the cue ball so that it follows to the far end rail. What do you think is going on?

the old style which is best is to use some outside english to overcome the so called push of the object ball.
easier than to try to hit a different spot on it.
that is not to answer your question just to add a thought.

yes i know but this way everyone gets it.
i called it so called push.
and as you found out yourself this is international

heck in the poolroom some think throw is squirt.

but your right.

Thx, then the contact point will be fixed only at a certain speed.... and this cue ball speed is ''felt'' thru yrs of play.
As the rolling cue balls speed is increased, the contact point will change meaning your must hit obj. ball slightly little thicker.
And when conditions are dirty and humid then a feel for that contact point ''must be developed''.

Simply use the correct contact point. You can use a quarter or less peace sign as a guide. It's only a few degrees and very consistent.

Dr. Dave showed that CIT can curve an object ball. So that.
It's all low speed/high friction stuff.

Spin (on the cue ball) induced Throw (to the object ball). You should know if you hit it wrong, after follow through, and if it is a good, well-maintained table, then everything should be right, the way you play it, for whatever you were trying to do. I probably did not even answer your question, but just posting my thoughts on spin induced throw. I actually did not even understand your question, lol. Too complicated for my understanding. I just know how to play. Do not know or understand all this stuff, put into words.
