Ball never touches bottom of pocket

In the case of a pool ball, what is the observation that best illustrates gyroscopic effect?

The author of the video was simply pointing out that there exists a secondary oscillatory phenonema not unlike a gyroscope under-going precession. As to whether precession is actually defined AS a simple harmonic oscillator I am not sure about.

If you are still curious here is the mathemaics behind it. As you can see the equations look similar to gyroscopic precession (Or do you want to bring up the difference between Einsteinian and Newtonian theories?)

This is a fun video, don't get caught up on semantic details!

Never seen it happen on a Diamond. GC and other brands...sometimes.

I was having a bad day at the SBE Seniors tournament one day. As a part of that day I hit a ball at what I would call medium speed into a corner pocket on a Diamond bar box and had it jump out onto the table. it surprised me and my opponent. Never seen it happen before or since.

Nah, just tired of the shitty game that you, Bob, and Dave play.

To answer your previous question, with the same ball velocity, the spinning ball will slide further.

Now you can tell me that is flawed because the spinning ball has more energy and, thus was hit harder. Then I can tell you that it doesn't matter because the only concern I have when playing pool is the results.

That won't be enough for you, so you'll low-key insinuate that I'm dumb, as if I, or anyone else cares about your opinion.

It's just exhaustion when people who fancy themselves as interested in science only play for their ego. Like you, Bob, and doc.

I was having a great day on a valley at the bar twenty years ago, pounded the eight in one side, it popped out of the other side, landed on the surface and slowly rolled into the original pocket.

On a drop pocket table I once fired a bank into the side, ob flew around the rim towards the opposite side and hit the back of that pocket and back onto the table. No lie it was ridiculous.

Dee, I have seen that twice. Both times on Valleys. I guess it just hits right in ball return with a lot of speed or maybe hits another ball hung up in the return.

I watched a few more videos on that channel. There's a lot of cool stuff, and he links the papers a lot of times.

Thanks for sharing that!

You are welcome. He is articulate and patient which is hard to achieve as an educator, something I need a lot more practice at.
 
Here's another one, @Bob Jewett, where your doctor friend and the famous windbag Neil Degrasse Tyson discuss the physics of bowling (yawn).

Note that in the video description they mention "gyroscopic effects" of the bowling ball. You'll have to watch the video to find out more. I'm sure as hell not going to.

Looks like your boyfriend got it wrong, the same as you in the last video (I peeked). Darn.

Here's a paper that might help you understand a little better...see attached.

That's it now, @Bob Jewett. If I keep doing your homework for you, I'll have to start charging.

I don't care whose opinion is correct here, but your language is blatant homophobia and you should be 86'd.
 
Lol. Dunno bowling balls - eccentric devices... Cue ball though, if you roll it center ball isn't that like a tire? Shouldn't it roll straight? Works for me when I need it. Wondering also if english works beyond the cloth friction. (?)
