Will potting angles change with the use of stun, follow or screw?

[Byrom]

You can straighten up a pot with side - turn a ball over ever so slightly I did it using top generally perhaps as the balls are in contact a fraction longer I am guessing but this is minimal as the balls are not in contact long - it is possible of course to change the angle as a kick can often change the angle of the ob yes?


Generally though the potting angle does not change much - but it is possible to impart a fraction - snooker players do automatically allow for this by hitting slightly thicker or thinner on certain angled shots but we do this because of instinct and hours of practice without actually realising why - -

The opening question does not ask about the white just the potting angle so maybe people are getting confused-

If you take into account the white in this angle thing of course you can change the angle of the white after contact with the ob hitting at different pace or with side or arc it with bottom top etc

But why is it important to know the physics of all this - have a look at a few shots get on a table and just do it - learn yourself.

I posted this question precisely because of trying to pot half ball blue with white in the same starting position. I could do it repeatedly with plain ball and follow but when i play with stun I always miss it thick.

Because it can cost you a lot of money? Check this out from Karl Boyes. Simple shot but he failed to consider all aspects of the shot, which required lots of spin for position.

Firstly, deflection. Not a problem at that distance, plus he uses a low deflection shaft. Secondly, spin induced throw. The ob throw to the right more than he expected. He failed to understand he needed to undercut rather than aim for the centre of the pocket. Thirdly, crucially, the spin on the object ball spat the ball out rather than span the ball in. The shot could not be missed without spin. Had he thought about this a bit more he would have won the match and may have been 50 grand richer.

This is my best guess at what happened with the shot - happy to be corrected.

Those of you who don't believe in throw effect, try the same thing with two basketballs. Same point of contact with no side and with side. The sidewards spinning ball will throw the contact ball off the normal 'potting line'. Basketballs will have huge amount of more friction so the phenomeon should be more easy to spot.

The same applies to cue sports, but the effect is far smaller.

Please do correct me if i'm wrong.

I would say he over compensated for the side and missed to the near knuckle, but I'm sure that's far too simple for you

[VillaGuy]

I do agree, stun, screw and top do affect the potting angle you should aim for. What the cue ball does in it's rotation obviously affects the side imparted on the OB, but like people have said it confuses you thinking about it to a minute detail that it's not worth thinking aout

[pottr]

Line of shot - The path the white needs to take to pot the object ball.

Angle of shot - The path the Object ball needs to take to hit the centre of the pocket.

If we can all agree on the above, then someone explain to me how the two stationary objects at the time of strike (The object ball and the pocket) can ever change as a result of where you hit the white?

The path from the object ball to the pocket is a straight line.

[Miig]

The point of contact stays the same, but the OB takes a different path because the sidespin from CB will cause opposite sidespin to the OB.

How do these pros make 147s but don't know about this, yet we are on here arguing about it? If it was in any way relevant wouldn't the folk who know about it be the pros, and Ronnie and Hendry would be on here arguing about where they went wrong.

[Miig]

Well I doubt most of the pros know even the basics of the physics behind snooker. And there's no reason they should, all they need to do is adapt and it comes with years of training.

And wether it is relevant or not, isn't the point for me. People arguing it's not possible or real is the point.

Here's a good article about the physics of billiards: http://billiards.colostate.edu/physi...cs_article.pdf
Ask yourself if you can explain it in the terms of physics how screw or top spin alters the route of CB after collision with OB. If you can't, do you think it's as pointless as throw?

What makes you so sure thay don't know about it?

[pottr]

We're not talking about side spin... talking vertical only.

[Miig]

Post #46 and #49 you did deny the effect of sidespin to OB, or i've understood you wrong. Either way i do agree that vertical spin will not alter the angle.

[itsnoteasy]

You genuinely think they waste their time on the physics of colliding balls? I will guarantee you none of this will help you pot a ball, but I can also guarantee you it will help you miss loads, if you fill your head with it.

[Slasher]

I think the effect is less with lighter balls.
With snooker balls the only thing I take into account is the cut induced throw for thinner hits, this is where I notice that I get slightly thinner cut angles with top or bottom, anywhere near center seems to push the OB wider, maybe some mistake this for a bad contact when it straightens up on them?
