Pay attention to the speed of the one ball. How can spin take any affect at that speed?
but if balls were farther apart
I meant to say the ob farther from the pocket
No matter how hard you hit the ball there is an instant the balls touch, at that moment of impact the draw is imparting top spin on the ob ball for that brief moment. The one ball that Efren hit was so close to the pocket you could not see the effects of the colission, but if balls were farther apart it would be more noticable. there are other factors that play into this aswell, IE. dirty ballsfriction from the cloth etc. hope this clears it up a little for you.
Well, my hands have been referred to as "frying pans" among other things (bear paws, etc.), but I just cannot get used to a shaft that thin. In fact, I just gave up on a 12.5mm shaft.
I think you posted the wrong link. I don't understand what you're trying to point out.
That's my link. I'm just trying to prove something to you. There was minimal spin imparted onto the one ball. You would think at that speed, the spin imparted would increase but it doesn't.
It's actually elementary stuff. Accelerating objects inside a moving vehicle is moving at a faster speed than the car. Same for spin on a moving ball. That said tho, the transfer is negligible in the pocketing of ob equation.
Efren didn't spin the ball.

You may also think spin helps move cue ball along the rails. It doesn't. "Running" English is commonly known to give the ball more momentum, but that's not true.

Here you're talking about effects of spin on the cue ball along the rails. You're wrong due to the reason I pointed out above.
This is a completely different matter. "At that speed", I agree with you that practically it won't matter (although there is still an infinitesimal top spin transferred to the one ball), but that was not my original point, and I thought it neither was yours.
No one thinks that "at that speed" the spin imparted onto the one ball would increase, but you. In fact, it is just the opposite:
The spin imparted on the one ball depends on the "time of contact", and the friction force between the cue ball and the one ball "during" the time of contact.
Obviously, the harder the hit, the shorter the time of contact, hence the smaller the amount of spin transferred.
Your analogy here is not helping. In fact, I have a hard time even making sense out of it. Accelerating objects inside a moving vehicle are moving faster than the speed of the car in which reference frame?

I'm not going to explain all this. It's easy to understand. He smashed the one ball. It should have jumped off the table. The sound of it rattling inside the pockets should tell you everything.
Are you kidding me? There was Zero spin on any balls until the cue ball made its way half a diamond from impact.
I hate all of you.
Don't hate the player, hate the game or physics itself, but it doesn't matter about the latter
edit: hint: just because you can't see it doesn't mean there was zero spin on the balls. I suggest you watch Dr. Dave's high speed videos. Later...
No, there was absolutely spin on the cueball before, during and after impact with the object ball.
It's okay, WE still love YOU.

Randy, won't draw on an cue ball impart enough top on an object ball to make it follow into the pocket when shooting a combo?
I think the draw on the cue ball starts the 1st object ball off with a little top which allows it to pick up the natural roll faster.. If that makes since.
