Stroke with no acceleration versus stroke with acceleration

I think you may start to find that stroking at slow speeds is one of the things that separates the pros from the rest of us. I think it was Mark Wilson that referred to it as "pro grade topspin" and "pro grade draw." The pros are able to stroke nearer the miscue limit with much purer form than most players. Watch their balls float around. They can really put the needed spin on a ball at slow speeds. We would be smart to emulate them. It's one of the reasons they can get around the table so well. By using the vertical axis and delivering a pro grade stroke you can really get some stuff done on the table.
Top players strokes are just purer all around. Straighter, more flowing with no jerks and spot-on tip-to-cb application.

Here I am, a mere mortal on the table having to play mind games with myself to keep my stroke pure.

You've heard about people thinking/saying "Ladies and Gentlemen" when stroking the CB. I've started saying "Pro Grade Stroooooke." The cadence is different but it's like a pep talk and reminder on each shot. Keeps me from getting the yips. And the drawn out stroooooke part keeps me from rushing the transition from back to forward on the final stroke.

It's kind of silly how mental this game is. Sometimes you gotta coax your body into not doing stupid s###! :)

If it works it ain't a placebo now is it? 😅
 
Not on straight shots, where the CB is fully stopped by the OB.

True.

But we can amend to note the countless players who cannot execute draw, both straight back and to a precise distance for shape, because they hit the cue ball hard, inaccurately (having been told their chief thought should be acceleration rather than a smooth stroke).
 
I think launching my cue stick like a rocket from launch horizontally has improved some of my stroke mechanics. My sensitivity to specific phases has gone up and my 14.1 breakshots are looking better than ever.

Refining my stroke using traditional techniques, made my bad habits worse. When it comes to trick shots and artistic pool, the stroke has to be perfect. Most pool players think of perfection as a wider range because the numerous ways to run a rack.

Artistic, Trick or Carom is the most mathematically precise, with possibly Pyramid being the top of the precision hierarchy in pool or billiards.
The "oomph" or conscious acceleration for most strokes IMHO should be for the first bit of the forward stroke (to change direction or get it going from a standing start if one has a long pause to complete the backstroke).

So if someone uses a 7-inch bridge, I tell them to put on the jets for the first inch or so only then let the cue stick glide/coast/accelerate/follow through, whatever you want to call it, without conscious effort. Without the conscious effort except for this early "go phase", longer backstrokes/bridges create automated speed control.
 
I have seen some scratches in a side pocket that you would be hard pressed to replicate with an object ball, and ball in hand.
I just had one last night! I'm on the 9. It was near the side pocket. I cut the 9 into the center of the side pocket. I'm thinking I'll sent the CB down to the end rail at the first diamond and back out to the center of the table, kind of a 2 rail, no way to scratch. 9B splits the side pocket, CB touches the rail about 1 inch from the side, it goes so deep and close to the corner pocket, 2 rails around and rolls at pocket speed in a direct bee line for the side. I actually think it took that CB 3 minutes to scratch in that side, but it sauntered up to the same pocket the 9 went in and just trickled over the edge into the center of the pocket.

I've never seen anything like it. I mean, the scratch was there from the beginning of time but how on earth... I could try to replicate that shot 100 times and probably not make it once. :unsure:

That CB can sometimes grow legs at the most inopportune moments. :)
 
Actually, a study that some biomechanical researchers in Austria did at a Eurotour stop found that a large majority of shots were played with zero acceleration at impact -- the cue stick was coasting at the instant it hit the cue ball. That is the most efficient way to hit the ball, all else being equal.

However.... For the break shot the players mostly were still accelerating when the stick hit the ball. I don't think they concluded anything about the reason for this but I suspect that if max speed is your main goal, you want to keep accelerating for as long as possible.

Of course the cue stick must be accelerated at some point during the stroke or it won't be moving. Most shots require the stick to be moving.
I believe the young Chinese players prove this...

Yep. Same with putting. The accel. phase is earlier than you'd think. Club/cue is coasting thru impact.

I think coasting happens breaking too. Its just that the accel. phase is earlier and much more aggressive than on standard shots making it appear as if accel. is still happening at impact.
 
A feather stroke is the easiest way to imagine a decelerating stroke. Its a pulled punch stroke for you fighters.

Zero stroke means the average velocity over the shot length and time is zero. The same as saying the stroke has constant velocity.

A constant velocity stroke is more of a push to roll the ball.

A positive stroke rolls and has other effects on the ball. Acceleration is transferred in the horizontal direction while the vertical forces create the magic cueball effects.

The best trick shot artists apply the correct stroke force to be successful.

Pool players prioritize shot making. My stroke was lacking so I retooled it with a trick discipline.
 
If you want to get an idea of what your stroke velocity/acceleration looks like check out the QMD3 digital stroke trainer/analyzer. In this example the cue is starting to 'coast' right before contact with the cue ball. The flat area in the middle of the stroke is the pause.

A robot could theoretically, perfectly execute any shot with a constant velocity, the acceleration is simply to keep the the tension out of the arm and keep the cue on the intended path.
 
I ordered this device from Seyberts and it should help me with my stroke accuracy, and hopefully acceleration. I think acceleration is something you want to keep consistent and smooth.

Any decent stroke contains acceleration and with most all good ones the accel. phase is done fairly early with more coasting than you'd think. Shoot some 6-7foot straight-ins and try to center cut it and park whitey. Your stroke will have to be pretty pure to do this with any consistency.

"Shoot some 6-7 foot straight-ins and try to center cut it and park whitey"

I think I understand that you mean stun the cue ball and have it stop in place where it hits the ob. Great indicator ! and not as easy as it seems.

All strokes accelerate at first, or they wouldn't move at all (I know you know that :)).

Shoot some 6-7foot straight-ins and try to center cut it and park whitey.
Also try stop shots from different distances and vary either the tip height or stroke speed (but not both) to make each distance work. Over time you'll figure out whether tip height or stroke speed is the best "control" for you.

Buddy is a monster player and somebody I haven't heard anything criminal about unlike some of the grand gentlemen of the game. However stroking in a tube is bad practice. The reason is simple, it takes a very contrived stroke to take the vertical out and to no purpose. Form a vertical slot, with two hardcover books for example, put a target where you can see it and stroke away. The vertical component at each end of your stroke does no harm. Only a few inches at the cue ball matters. Most of us wasted time and harmed our stroke practicing with longnecked bottles trying to stroke perfectly straight.


Responding to a handful of posts, coasting with a pool cue is evil! Looking at coasting alone, our stroke needs the support of contracting muscles. We get this by trying to accelerate through the cue ball.

Accelerate, transition, coast. That state between accelerating and coasting is a huge issue. How many sports and activities advocate follow through? Follow through after contact does only one thing, prevents transition before contact.

There are many muscles in the arm although we often only consider the primary muscles. These muscles never transition perfectly evenly and this is where our comparison to a robot breaks down. A machine has support and can be easily adjusted if need be. We don't have these same luxuries with our muscles.

Using an open bridge, shoot a medium speed shot of moderate difficulty and stop two inches past the cue ball. A machine can easily do this ten thousand times remaining straight within thousandths of an inch from start to stop. Did anyone try this only ten times without obvious errors? We are vastly superior to machines but we also have issues they don't have.

Until we can transition perfectly and provide directional support while coasting remaining in a steady state is better. Since all strokes start with acceleration, going through the cue ball with acceleration seems best. I once experimented with an early burst of acceleration and maintaining a steady speed but was unable to do so. I can't say if the muscles provide adequate support in this state or not. Still a transition involved though not as great of one.

From the Fundamentals chapter of my book.

I personally believe in the continuous straight, horizontal and vertical stroke method, and not pausing. If the player interrupts the rhythm, he may lose the timing and tempo he was trying to achieve. Another very important part of the stroke is crescendo, (increasing speed), never decelerating. Just remember, whatever number of warm-up strokes you choose to take, embed that into your game.
By no pause do you mean once you get down on the shot and start stroking the cue you never stop the cue again until the shot is over??
 
Reviewing my personal journey in pool development, my stroke has gone from a wild motion of thrust to highly controlled burst strokes.

Masse shot clearly has acceleration, if your not sure blame Isaac Newton.

Level playing cue shots have more room for mathematical variety.

The three classifications of strokes are a negative (decelerating), positive (accelerating) and a zero acceleration.

Early players are unmeasured with positive stroke. Competition players demonstrate zero stroke and the talent revolves around stroke consistency and gameplay.

The negative stroke is great for practice and study. A negative stroke exercise is exactly what it sounds like if you lift weights.
