does the weight and hit of a cue effect the ability to move the cue ball. is there a different technique different players use when stroking the cue that light or heavier would be better for playing style. or is the design of the cue taper wood type stiff verse softer play more roll in cue ball movent.

It totally depends on the ability of the player.

F=MA. Force equals mass times acceptation is the model.

If a player has the ability to put a big move on a cue ball with a potential to reach 30 mph for example, he wants a light cue around 17 oz. Give or take. Light cues can accelerate faster.

If a player does not have that ability then a heavier cue with more mass will help them.

I knew a 75 year old retired doctor you played every day and did some research on the physics of this. He told me that there is a point where too heavy becomes counter active to those with limited athletic ability. This weight range out of the improvement envelope was described to me as 26 oz.

As far as shaft taper is concerned, I would think that a stiffer shaft with more climb would be better than a skinny super pro playing shaft for example.

F=MA isn't relevant. It's what people who know nothing about physics always spout off.

One needs to look at conservation of energy equations and impulse transfer of energy equations.

This has been discussed too many times in relation to break cues, I'm not going to repeat it.

ElCFrio,

Re read the OPs question. It was directed at Cue weights and differences concerning different players.

Conservation and transfer of energy are relevant to any pool shot but why do you make a statement and then run away. If you don't have the time to do so, why engage in the first place. One would have to question your motivation. Are you a long time lurker with this information that has been posted way too many times or a confederate screen name trying to stir the pot of discontent. I don't really care so much, Just asking? Who are you anyway? An anonymous screen name is always a big question mark?

Maybe I am wrong but I thought we we discussing controlling the maximum acceleration or the speed the cue ball measured at the moment it leaves the tip of the cue in reference to different players and cue weights.

I have been on this form for many years and would love to hear what has been posted too many times????? Please instruct me if you have a minute.

Elbow droppers like lighhter cues.
Stroke slippers like heavy cues.
My observation.

The kinetic energy is equal to 1/2 the product of the mass and the square of the speed. In formula form:

E=1/2 mv^2

where m is the mass and v is the speed (or the velocity) of the body. In SI units (used for most modern scientific work), mass is measured in kilograms, speed in metres per second, and the resulting kinetic energy is in joules.

There is a point where no more energy can be added to the cue as weight is added because of the limit of the shooter to accelerate the cue.

Not only is that to be considered but..... also the ability of the tip and associated cue behind it to transfer that energy to the cue ball......... a soft spongy tip may lessen the energy transfer. A hard tip may actually gain a little speed as the cue ball and the tip flex and spring the ball off..... assuming that the velocity of the cue is not slowed by the hit on the mass of the cue ball................

I have seen a few tests and the outcome is that a cue of about 15 oz and a very fast arm may be the best.

just how I see it................

I asked this question because i am shooting with a predator LE 3 with a Z2 kamui soft black and the cue is about 17.8 ozs with a big weight bolt so it is rear heavy. I feel on certain shots the cue kicks back like theres not enough cue to make the cue ball due what I want. I was wondering if I had a brass pin installed to move the balance point foward and could get somewhere over 18 ozs cause the cue does feel very light. or Is it the way I deliver my stroke first time I felt this I play as a 7 and im 6'5 285lbs

I didn't have the time to completely answer, I mostly just wanted him to know that he shouldn't listen to you when you say that F=mA is relevant.

Look up the equation at the bottom of this page: http://www.real-world-physics-problems.com/elastic-collision.html Or look at Dr. Dave's explanations...which have been posted ad infinitum on these boards.

Yes, a faster moving lighter cue may provide more speed on the cueball than a slow moving heavy cue.

Yes, for breaking, a lighter cue is likely better.

The OP is asking about playing and I can't say that I've seen any evidence that it matters.

They used to say that they used heavy cues before worsted wool because the heavy cue moved the ball easier, but that is only if the contact velocities stay equal.

Again, Rick, I'm likely to call you out on everything that you post when you obviously have little or no clue about the subject. Hopefully nobody will seriously injure themselves with an exploding car battery charger if I do that.

Damn, you ain't small.

I have a buddy who is about like you who recently went from a 20oz cue to a 18-18.5. He loves it.

I'm 6'3" and 170, I play with a 18oz. cue.

They make stick-on lead weights for different things, you might grab some and put a bit on your cue to see how it affects it for you.

El CF,

It's OK to call me out if it makes you feel warm a fuzzy.

As I said, why post and then run away if you don't have time.

What did you say your name was?

Really? How do battery chargers blow up? Do they explode and turn into missile projectiles. What is your anonymous theory on this one. Inquiring minds wish to know.

In my experience, those who move the cue ball more, the ones who are described as having a great stroke, are really the ones who can hit closer to the miscue limit at faster cue speeds.

Cue ball spin is a function of the how much energy is imparted on the cue ball, and where it's imparted.

Those who struggle with getting the cue ball to spin as much as others usually can't hit the cue ball as far from center. If they try to go further out, they go too far and go past the miscue limit.

Here are 2 examples of excellent stroke players with different styles. Both are really good at spinning the cue ball, but they do it differently.

Corey Deuel and Mike Dechaine. I've played and talked with both of them and studied the shots they play what's happening with the cue ball.

Corey likes to hit very hard and very far out on the cue ball. He gets tremendous spin which creates those crazy curving cue ball paths. The cue ball has tons of spin, but not as much forward speed as you might expect because he hits so far out on the cue ball.

Mike likes to stay a little closer to the center of the cue ball and get his spin through power. He has a deceptively strong stroke. He often plays for less angle on his shots so he can hit the object ball more full and stun the cue ball to the rail. Hitting it full kills some of the cue ball speed from that powerful stroke. But, because he still has the side spin when the cue ball hits the rail, he also gets crazy big spinning curving cue ball paths.

Both are amazing feats of talent that not everyone will be able to do. Of course, they both have many other types of spin shots and very high level skills.

My point is that what we call a stroke is really being able to deliver the tip to the desired spot on the cue ball, with the right amount of speed, and traveling in the right direction.

It's really that simple.

Royce-

There you go again staying on topic. Will it never end?

I think that you are right on target. Thanks for your lucid observations.

The battery charger blowing up was not meant to be literal. You give ridiculous and incorrect, sometimes dangerous advice and I posted to point out that you aren't knowledgeable on this subject if you simply state that 'its F=MA'...because F=ma doesn't apply.

I also came back and answered.

My name has nothing to do with you being wrong.
