No need. I've seen the impact a good teacher can have on my kids, and I
consider it an extremely honourable profession. BTW, I'm from Canada,
Toronto to be specific.

Tell me, is this supposed to be exclusive to rsb....this 3d
aspect view? I'm just curious. I do think names like "roll axis" and
such would be better, because they imply functionality, and to many of
us the words horizontal and vertical have other pool definitions. I'm
not saying its not necessary, but can you give some examples when this
would be needed? Can you also tell me what your definition of squirt
is, and throw? It seems to be different around here. And when I say
level cue to you, what comes to mind? Me, I assume the slight downward
angle.

I do think it's necessary, the 3D view, for this discussion, but not
most of the time. As Bob said, sometimes the situation dictates the
precision of language needed. Vertical hasn't changed, but there are at
two important horizontal axes on a pool table, so for this discussion we
need to use terms describing each.

A level cue, for most discussions, is one as level as you can make it.
For this discussion, however, we need to be more precise and we mean a
cue parallel to the bed of the table.

As for the curving of an object ball, I thought it was just a
difference in the wording, but now I'm not so sure. I call a curve any
line thats not dead straight. I did put this shot up to specify.

Well, I imagine a mathematical pedant would call a straight line a
special case of a curve ;-). But no, for this discussion, I would call
a curve anything other than a straight line. This could include part of
a circle (an arc) or other regular or irregular non-straight shape.

With respect, Bambu, I'd suggest we leave your shot out of the
discussion for the time being, then return to it after the discussion of
physics, to avoid clouding the issue.

Cheers,
Dean

No problem dean, we will put that shot on hold for now. Let me
cut to the chase. Ron says throw occurs in straight lines, and I dont
agree. This seems to be the crux of the issue. But let us discuss
straight lines first.
I say one of 3 things must occur for any ball to travel dead
straight. 1. A full hit with no English, regardless of center follow
or draw....or even speed to a large degree.
2. On a cut shot, when you use outside English to cancel out the
throw. The third way would be to eliminate all or much of the throw by
shooting hard. Even by hitting hard, or using outside English to
cancel out the throw....you are not making the line dead straight. What
looks straight, really is not. In doing this you are straightening
your object ball out as much as possible, but not 180 degrees. As I
have said before, rarely do we see dead straight lines on a pool
table. We think we do, because the human eye is not capable of seeing
the curve unless its done very slowly.
We see it most often when shooting say, 2 glued balls which do not
line up dead into a pocket. We tend to think of these shots as throw
shots, but in reality you are using throw every time you cut a ball
in.
If the line of throw were truly straight, any speed at the same
contact point using the same english would result in the same result.
Throw is speed dependent. I'm saying the slower the hit, the more
throw you impart, and the more slight curve you will see on the part
of the object ball.
Further, an object ball will not react the same way a cueball
would, because there is no squirt involved, only spin. I compare this
slight curve to the top half of the dotted/spiraled line in fig. 2,
just much much less dramatic. I have no other reason to think an
object ball would not act like a cueball, just without the squirt and
with alot less spin than a cueball would get.
This is consistent with this site:

http://www.easypooltutor.com/article252.html
The amount curve generated is generally dependent the following:

2. The amount of spin on the cue ball. The more spin on the cue ball,
the more "curve" is generated on the object ball.


What I am saying, is that if you hit a cueball slow enough and with
enough English, an object ball will react as if it were hit with a
magic cue that had so squirt.....just far less dramatic.

Contrary to popular belief, I have not ignored the 3d aspect
which has been described to me. And I think I have some answers too.
(Go ahead and roll your eyes, its ok.) But before I continue, I want
to make sure on what we disagree on so far. Thanks for your help,
dean.
I am not ignoring the rest of the group, and I am sorry I dont
have time to answer every post right now. To preserve my sanity, I
really think its best to continue this with a fresh start. No offense
to the rest of the group.
