Geomtry or Physics, what's more important?

prad said:
When executing a bank shot, geometry is what i see in my pre shot routine. And physics is what happens when i execute my shot. A combination of these two is what i call a feel of shot ( geometry + physics), the reason I put geometry first, cuz a player is not going to execute a shot if he/she don't see it in the first place. After seeing a shot how a player hits it i.e. physics part, collision of balls, speed etc. comes to play.
For me both geo and phy plays an important part in pool.

Ok, I agree, geometry is what you visualize, but physics is what actually happens.

I am sure that the physics of the rail compressing affects it, and of course left or right english affects it. But, is't angle in = angle out basics behind it?

Thanks

Angle in = angle out

1. angles are Geometry not physics
2. Vectors are physics and would apply to pool - specifically the normal and tangential components of vectors

This is a really cool Mathematical description of what happens when playing pool. Once again, good luck :

I don't know the first thing about the human digestive system...but I eat and sh1t just fine.

How about some more stupid questions:
What's more important, addition or subtraction?
What's more important, gravity or mass?
What's more important, a triangle or a circle?

You'd have to not only leave out rail compression and cue indiced sidespin, but also natural roll on the ball, collision induced sidespin from the CB smacking the OB, dirt and friction, and a bunch of other things.

Basically to make pool balls behave like a geometry textbook, you need to remove dozens little physics-related things, until your bank shot has about as much in common with geometry as a free throw.

I think the whole pool = geometry thing comes up because inexperienced players (not meaning you just the non-playing public) think half the shots in pool are banks, not realizing that bank shots are more of a last resort and generally avoided because all that physics stuff makes them hard to aim. You can play ten racks in a row without having to once think about "angle in = angle out".

I agree with it being 110% physics, the only thing I think of really would be an angle bisector, which would make it be angle in angle out, only if to hit dead center, no english at all, to where I need to hit the rail on a kick shot. For example the CB is by the corner pocket, and the OB is right in front of the side pocket on the same side, but there is a ball in the way stopping me from making a light cut on the ball into the side pocket. I would hit the CB into the diamond in the middle of the side pocket and the corner pocket, making the CB hit then OB into the side pocket, by kicking it from the corner pocket into the rail and into the OB by the side pocket.\

Hope this makes snice, I am just getting back into pool. I really need to play a couple more games to get my feel back. I just picked up a cue stick for the first time last week in 2 1/2 years, and I couldn't hit S**t. I think the game will came back to me pretty quick, I just need to hit a few balls.

I kind of agree, the most important thing is to make the OB into the pocket.
 
for those of us that didnt read all the posts
