Top 10 misconceptions in pool

Post by Phong Do Kho » Thu, 25 Jan 2001 04:23:05

This is taken from:
http://SportToday.org/

10. Only guys can play pool.

9.I missed because the table wasn't level or the cue wasn't straight or I
was too drunk or ... (In fact, I missed because I failed to take
everything into consideration.)

8.Hitting the cueball ***ly will cause it to stand still after it hits
the object ball. (No; Hitting the cueball so as to impart just the right
amount of backspin causes it to stop dead after hitting the object ball.
Of course, that assumes the shot was perfectly straight and the cue ball
and object ball have the same weight.)

7. Balls bounce off the rails like light off a mirror. (No. The angle of
incidence does not equal the angle of 'reflection' in pool bank shots.
Learning how to predict the angle is a science, not a mysterious art.)

6. Great pool players win because they can make impossible shots. (No.
Well, actually, they can do this. But, more importantly, they use tactics
to place spin on the cueball so as to position it for the next shot. This
is why top-notch pool players seem to face a larger number of easy shots.)

5. Heavier cue sticks necessarily break better than lighter ones. (No.
Work out the physics; what really matters is how much energy can be
imparted to the cue ball, which depends on how much energy can be put into
the cue stick. The energy in the moving cue stick is equal to one half its
mass times the square of its velocity. Using a slightly lighter cue stick
means you can achieve a higher acceleration with the same force of your
arm. The slightly increased speed has a squared effect in the energy
equation and yields more energy. Switching from 21oz to 19oz makes a world
of difference.)

4. If the cue is kept level, contacting the cueball purely left or right
of its center will make it curve as it rolls. (No. The rolling cue ball
can have two completely independent components to its angular momentum.
Basically, this means that it can rotate in the manner of a top while
rolling slowly forward along a straight line. In general, spin on a cue
ball is of two types; follow/draw is the spin like tires on a car, while
English is the spin like a child's toy 'top'. Seperately, neither one will
make a ball curve! If they are combined - e.g., strike low-left giving
left English and draw - then the spin is called masse (mass-ay), and the
ball will curve as it travels.)

3. Cut shots are harder than straight shots. (No. Work out the geometry;
if one considers how slight changes in the initial cue ball direction
affect the object ball's final path, it can be seen that cutting the
object ball about 35 degrees from the path of the cue ball is the easiest
shot. Straight shots, and cuts shots close to 90 degrees, are the most
difficult shots. This may be the single most useful factoid in pool.)

2. Stance, grips, bridges, mental state, wishing, follow through, etc...
affect the shot. (No. The following is about all that matters: spacial
orientation of the cue stick at the moment of contact, velocity of the cue
stick, geometry of the cue (is it cylindrically symetric and does its
center of mass lie on the center-line of its geometry), the flexibility
and resilience of the cue stick, the coefficient of friction between the
tip and cue ball, the size of the surface area over which the cue tip and
cue ball are in contact, the duration of the contact, the elasticity of
the collision, the relative weights of the cue stick and cue ball, and the
location of the contact point on the ball and on the cue tip. Everything
else improves your chances of getting these things right, but has no real
effect.)

1. Skill can beat pure luck. (I've been on the wrong end of this fact
several times. :)

It's not exactly mysterious, but it's more art than science.  You have
to judge the spin and speed on the ball, which is a matter of "feel".

I don't think I agree with this either.  Do you know why it's said?

I don't know why, but I find that it's true, making a long 30 (ish) degree cut
I find, is alot easier than shooting long and straight.

However, about the cut shots close to 90 degrees, it's obvious that the
precision needed is much higher, and I find that you are forced to shoot harder
to transfer more power (provided it must travel a notable distance).  So the
extra influx of power makes the shot less reliable too.

Cut shots ARE harder than straight shots.  The angle factor of the effective
target size is approximately cos(angle).  I have no idea what the above 35
degree thing is about.

Do you think perhaps it's "the importance of the half-ball hit" after a
little game of telephone.

If I'm not mistaken, isn't that the angle (35 degrees) which yields the least
contact induced throw, therefore is the most "pure" shot?  I think Kohler talks
about it in _The SoPB_.  I think he also had some chart about contact point
margins of error for various cut angles.

In considering the following diagram:

START(
%Ar6I4%BP7[0%CY1K1%Pr6R7%Qq1M5%Re2M3%S_5V0%Wr6K4%Xr6R4%YR6Z9
%Zr5R7%]Z8K8%^r5R6
)END

I find it's obvious that yes, shot A is the easiest, short, and straight, and it
doesn't get much easier.  However, given the option, I find that shot C (long
cut) is easier than shot B (long and straight). Am I alone in feeling this?

Furthermore, an article written by Jim Meador found here:
http://www.billiardworld.com/straight.html
It states that the long and straight is a shot that many players find
difficult.  Perhaps it is this by which the author meant that some cut shots are
easier than straight shots.

Perhaps this is it.  Natural roll carom angles corresponding to approximately
half-ball hits (around 30 degrees) do not change much compared to the object
ball cut angle.  For example, see problem 4.17 in APAPP.  If the object ball is
cut at 26 degrees, the natural roll cue ball will roll at 33.64 degrees; if the
object ball is cut at 30 degrees, the cue ball will roll at 33.67 degrees.
That is, for 4.0 degrees of change in the cut angle, the cue ball changes only
by 0.03 degrees.

However, this is stability of the cue ball trajectory, not the object ball
trajectory.  If you miss the object ball cut by 4 degrees, then the object ball
misses by 4 degrees, simple as that.

Considering your diagram I think that at least one reason shot C is easier is
that you have a cushion right there to use as a visual aid.

Perhaps we need to define "easier" in this context.  A shot could be "easy to
hit" or "easy to see" or both.  I think your shot B has a target that is easier
to hit (larger, closer) than your shot C, but not necessarily one that is easier
to see (no obvious visual aids).

I have more thoughts about straight shots vs. cut shots.  Miss the OB contact
point on a straight shot and throw will tend to correct your error.  Miss a cut
shot by overcutting it and throw will tend to correct your error.  Miss a cut
shot by undercutting it and throw will exaggerate your error.  So straight shots
may have some built-in correction mechanisms that only work half the time on cut
shots.

I'm not a physics guy, but we have some on staff here that might address this.

Looks like you need 5, 8, and 9.

5) Pool gloves are fashionable, even the dapper black ones.

8) Follow is as easy as draw.
    Bullshit - Follow is MUCH harder to master than draw.

9) To be a pro, or play at that level, it's all TALENT.
    Heh, talent may be a factor, but it's all practice.  I will defend this
if anyone wants to challenge me. :)
