New Screw Back Technique

[Nic Barrow]

Hi Guys
Many players have trouble miscuing - or simply not screwing back at all...
Here is a routine I have found really helpful to players of all standards: https://youtu.be/97SacEsVaV8
Let me know what you think and I will reply to your comments here where I can

Thanks for making time and get here.
Very useful tactic imo . also to get used to put less effort on cue .

Abit off the topic question in regards to your video ,
But , would be fair to say, the butt diam is a Very Important factor for a player. this in order to close the grip consistently and keep the cue stright during dilevery ?
I'm asking this bcuz i've noticed many players are easy on this part once they decide to buy a new cue . Sumtimes
They do'nt even care about , what's the but diam ?
Which is imo the main part of cueing during scrw back shot .

Reminds me of Sheldon Cooper's 'Fun With Flags'

Once again something pure and simple made to look ddddddeeeeeeeeeeeeeeeeeeppppppppp, innovative and perceptive.

I quite liked that, it's very easy to forget what it's like when you are learning. I don't think I have come across anyone who didnt think( when first starting out) that more screw meant hitting the cue ball harder and with more effort, I include myself in there as well, this is a fine video showing it's the cue that does the work. From my point of view getting this in your head,that it's all about the cue, can't half bring your game on and improve your technique all round very quickly. Tension is a killer in this game.

Looks like a mike wooldridge cue there. What is your opinion on the blackspin ferrule? Does it help the screw back?

That would be physically impossible, cue ball reaction is a product of speed/mass/contact point, not much else matters.

May i ask what you mean by ,, Mass ,, ?

are you suggesting, the heavier the cue, the more ( better ) CB reaction you get?

Do'nt get me wrong. It is not a criticism towards your opinion.
It's just a question?

[Slasher]

Yes, more weight will apply more torque to the Cue ball but remember that weight has to be accelerated so too heavy and you won't be able to generate the speed.
Just to be clear this is not an opinion it is simply physics 101 Think of it as trying to knock a nail in with a plastic toy hammer.

agreed with that one .

Physics 101 is in regards to Mechanical purposes (robats ? . machines ? ).
You can't apply that to human science.
simply bcuz we (as humans) are able to adjust our technique. We are not Robats.

what you are indicating here is, player A with an 18 OZ cue is able to play the scw back shot and get alot more CB reaction comperd to other player who's useing a 17 OZ cue. Right ?

well ,honstly, this one is new to me.

cheers for replay.

[Slasher]

yes if the cuWe are not Robatses were travelling at the same speed and contacted the same point on the cue ball the heavier cue would get more reaction

"We are not Robats" Ramon, the cue ball does not care, physics is physics.

Hence my previous post.

diff players have diff techniques / diff cue speed and so on.
All which is the reason why you can apply physics to the robats , and NOT TO US (players/ humans ).

Stephen Hendry played for many years with a 17 OZ cue. and he was able to create more CB reaction/ spin , comperd to sum other pros with heavier cues. how com ??

the idea that a heavier cue is needed in order to create more CB spin , is simply Not true .
( unles you give that cue to a Robat and program him to play the game , which in that case I would agree with you ).

I did not say you need a heavier cue to generate a lot of reaction but it will generate more, there is no getting around this scientific fact. Hendry had very accurate cueing and like Trump, Murphy etc he could strike the cue ball exactly as intended even with a lot of cue speed, even many pros struggle to generate high cue speed without over gripping the cue and losing accuracy on the cue ball. You need to come to terms with the fact that the cue ball does not care if it was struck by Ronnie O or Asimo, it makes no difference whatsoever.

The main parts are speed/mass/point of contact, the effects of tip hardness is slight as well as angle of attack but that is it. Ramon, you cannot break the physical laws no matter how hard you try especially not within 1/1000 of a second of contact.
And if you are really unconvinced I can show you the math, it's not hard to find as it is 400 years old after all and taught in elementary school.
What the video demonstrates clearly is that the grip is responsible for most cueing errors, if you contact that cue ball in the right spot you do not need a lot of speed to get a good reaction. Now, add a couple ounces of mass and ramp up the speed and you get a full table draw shot.

The Physics Classroom » Physics Tutorial » Newton's Laws » - Newton's Second Law of Motion

Newton's first law of motion predicts the behavior of objects for which all existing forces are balanced. The first law - sometimes referred to as the law of inertia - states that if the forces acting upon an object are balanced, then the acceleration of that object will be 0 m/s/s. Objects at equilibrium (the condition in which all forces balance) will not accelerate. According to Newton, an object will only accelerate if there is a net or unbalanced force acting upon it. The presence of an unbalanced force will accelerate an object - changing its speed, its direction, or both its speed and direction.

Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

The BIG Equation
Newton's second law of motion can be formally stated as follows:

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
This verbal statement can be expressed in equation form as follows:

a = Fnet / m
The above equation is often rearranged to a more familiar form as shown below. The net force is equated to the product of the mass times the acceleration.

Fnet = m • a
In this entire discussion, the emphasis has been on the net force. The acceleration is directly proportional to the net force; the net force equals mass times acceleration; the acceleration in the same direction as the net force; an acceleration is produced by a net force. The NET FORCE. It is important to remember this distinction. Do not use the value of merely "any 'ole force" in the above equation. It is the net force that is related to acceleration. As discussed in an earlier lesson, the net force is the vector sum of all the forces. If all the individual forces acting upon an object are known, then the net force can be determined. If necessary, review this principle by returning to the practice questions in Lesson 2.



Consistent with the above equation, a unit of force is equal to a unit of mass times a unit of acceleration. By substituting standard metric units for force, mass, and acceleration into the above equation, the following unit equivalency can be written.

1 Newton = 1 kg • m/s2
The definition of the standard metric unit of force is stated by the above equation. One Newton is defined as the amount of force required to give a 1-kg mass an acceleration of 1 m/s/s.

Yeah, but does Newton's first law apply to Ramon's Robats? I think we should be told.

are we still talking about snooker are having a physics lesson.

i'm sure when i am playing snooker the last thing on my mind is Newton's Law...Lol
