wrong. very very wrong.

gravity is ALWAYS acting upon the cue ball. before it is hit, as it is being hit, and after it is hit. the instant the cue ball leaves the pool stick, it immediately starts slowing down, due to the friction caused by gravity. When the cue ball strikes the other ball, the cue ball stops, due to the opposing mass of the other ball AND the friction of the table.

are Truthers and physics, mutually exclusive?

The cue ball does not come to a stop because of gravity. It comes to a stop because of what it hit. Another ball.

Is English your first language?

And thanks for the comparison between the World Trade Center towers and solid billiard balls. Very very precise and accurate.

Next you will be comparing the WTC towers to a chicken. Or a graham cracker.

:p

I guess we should construct our buildings like cue balls from now on. Thanks to our intrepid 9/11 truthers, nobody shall ever die in a building collapse again.

Thanks guys!

gravity has NOTHING to do with the cue ball's arrest? nothing at all?

are you SURE about that?

what do you think would happen if this was done in outer space? do you think the cue ball would still completely stop moving?

gravity is acting upon the other ball. gravity is pulling the other ball against the felt of the table. the friction caused by gravity and the felt, makes it much more difficult for the ball to move. if the table was teflon, results would be quite different.

if pool tables were covered with teflon and not felt, pool would be a very very different game. in fact, there would be NO game, cause the balls would bounce all over the place, for a much longer time.

No answer from debunkers. How surprising. Good night. Have a good time in your little club house here slapping each other on the back.

For what? I have no idea.
 
This is almost as good as as comparing the WTC to a BBQ grill. Thanks for the entertainment.

Well, I think he is just talking about conservation of momentum, where the secondary object receives momentum from the first. In this case, the 8 ball gets some of the momentum of the cue ball.

But what about gravity? If we are going to use a pool table as a demonstration, where is gravity in the equation?

I think we should put the pool table at an angle, and shoot the cue ball down hill at the 8 ball, and watch both of them speed up.

Does he address this at all? I am not going to waste my time with the whole thing when his first point is so pathetically stupid.

that is one remedy, or as the spoiler says you just add top spin to simulate the effects of gravity, the cue ball will continue forward, just as the upper block.
 
the cue ball is moving horizontaly, and being slowed down by friction caused by gravity and the felt table. the 8 ball has gravity acting upon it, as friction is holding it to the felt.

this is a HORRIBLE analogy to the WTC towers, as the top section of the building fell vertically, with basically NO force acting upon it (except air) until it hit the undamaged sections of the tower.
 
Man I want to go play pool with some of you people, then every time the cue ball doesn't stop dead upon contact I can laugh my arse off at you and every time I make the cue ball do something that you think is impossible I can laugh at you some more. I might even drink some aiming fluid to make it even more enjoyable... for myself.

The shot that makes the ball actually stop dead has a name, it's called a stun shot and it requires that the cue ball starts off with backspin and that, at the point of contact with the object ball, the back spin has just stopped. Stop the backspin too soon and the cue ball will follow through the contact point. Too much backspin and the ball will draw back towards the player (this is assuming a straight on shot of course).

If you hit the cue ball dead center it will always go past the point of contact because the friction between the ball and the felt will impart a forward spin to the cue ball very shortly after you hit it. Again this is assuming that you are hitting a single ball and not a cluster of frozen balls.

The gravity doesn't slow the cue ball down except when it is traveling. What the cue ball hits is what stops it. That would be the other ball. In fact the only time gravity is at work on the cue ball is when it is traveling at a high velocity before it even hits the other ball. Once it hits the other ball it's all over. It stops.

IF it isn't traveling, it is stopped, so how could something be "slowed" when it is at rest? Are you drunk, or simply have no understanding of junior high physics?

On earth, anything you roll or push on a flat surface (or any surface for that manner) will EVENTUALLY stop, with nothing in front of it, due to the friction caused by gravity acting on the object.

No one here is saying that the cue ball doesn't stop when it hits the second ball in SOME cases. They are saying that the ball would EVENTUALLY stop regardless, due to friction, which is acting to slow the cue ball down from the moment it is set in motion.

Got it?

As well, if you have played any pool, you will know that the cue ball does not always stop after it makes contact with the ball (ever sink the cue ball by having it follow the ball you hit into the pocket?).
