Spin Doesn't Transfer from CB to OB

Exactly. I'm not sure why anybody is arguing otherwise.


It makes for interesting discussion among bored pool players. Just because you cant see it doesn't mean its not happening. If a tree falls in the forest and no one is around to hear it, does it still make a sound??? :confused:

I understand and agree but regarding to the tree falling I've always thought the relevant part is not whether it made a sound but whether it is has fallen. The fact it is on the ground would indicate it has fallen. It would be a reasonable assumption it made a sound when it fell.

Actually it would have generated a force wave that could be classified as sound if there were auditory detectors present to measure it. The lying tree could have also been gently placed on the ground by a variety of means. It would be reasonable to assume however that anything which crashes into a significantly hard surface will produce a sound. Just as surely as one spinning object will cause a stationary but unfixed one of equal weight to spin.

Chinese version of that...

实际上它将引起可能分类为声音的力量波浪,如果有当前听觉探测器测量它。说谎的树在地面上可能轻轻地也被安置了通过各种各样的手段。假设碰撞入a的那任何然而是合理的
 
I did not even bother to watch nor read much of this thread! That being said, anyone who thinks that spin is not transferred to the object ball is smoking some serious crack;)

To those that believe it doesn't transfer, have you ever banked a ball with spin?? That tells the entire story for me!:)
 
This video and discussion has come up before in the past. The very first shot in the video clearly demonstrates that both throw and spin transfer are occurring. The right side side throws the OB to the left and imparts left (clockwise) sidespin to the OB. That's why the stripe of the OB does not remain vertical, as it would with no spin transfer. The OB stripe wobbles because sidespin is imparted to the ball.

As others have pointed out, you cannot get throw without spin transfer. They come hand in hand because they are caused by the same friction force between the balls. Diagram 1 in the following article illustrates what is going on: "Throw - Part VIII: spin transfer" (BD, March, 2007). And the following super-slow-motion video clearly shows the effect: HSV A.66 - Straight-on shot with english and slow speed.

The only time there is no throw or spin transfer is with "gearing" outside english (or with a straight stop shot with no sidespin). The following video explains and demonstrates this effect: HSV B.33 - Outside english gearing, and cut and spin-induced throw. And more information can be found on the outside english resource page.

For people who want more convincing concerning spin transfer (from either a cut angle or spin), the following resource page contains numerous videos, instructional articles, illustrations, and examples showing very clear evidence for spin transfer:

There are certain types of shots that are not possible without spin transfer. Here are some examples:

NV B.20 - Spin transfer bank shots
NV B.22 - Two-times and three-times across bank shots

And more can be found on the spin transfer resource page.

For those interested, Bob Jewett and I just posted a new video dealing with "gearing" outside english. Here it is:

We welcome comments and questions,

Of course it does. Set up a shot with a striped ball and hit it medium stroke with a lot of spin and see if the stripe ball rotates a little.
I have had two frozen balls that did not look like the front ball would throw enough no matter how soft I hit them. But if throwing the object ball to the left I would hit the front ball with extreme left hand English and it would spin the front ball more left then with a center cue ball hit.
Making frozen balls is an art form. a lot of factors there-distance to pocket-are they solidly frozen or just real close. Years of straight pool playing will give you a good education on how to make frozen balls.
 
I would love to play banks or one- pocket with anyone who claims spin doesn't transfer....
......and guarantees he won't use said effect.
 
Unless my terminology is off, I've always considered spin to transfer. I say this from all the one pocket I've played and I know the only way to make certain banks that I do I have to change the angle on the bank im shooting by using spin on cue ball. Sorry if we are talking about diff things.
 
"Truman," and Vernon Elliot were famous for this technique.

That's for sure, most bank pool players use a "Touch" of hold to increase their "pocket zone" (they also can widen the angles at will using spin)...."Truman," and Vernon Elliot were famous for this technique....."Bugs" was pretty good at it too. ;)
