    Does anyone know the coefficient of friction between cue ball and tip?

    How does it detect miscue?

    Does anyone know the coefficient of friction between cue ball and tip?

    Can't belive I accidentally have you all discovered a new feat! haha. I'll use "question" post in the future too.

    I like that "mark as solution" feature

    Does anyone know the coefficient of friction between cue ball and tip?

    Yes. But Dr.Dave thinks it's not as simple as that, he said, https://forums.azbilliards.com/threads/premium-chalks-%E2%80%93-are-they-worth-it.558248/page-6 That's why I want to understand this more. Do you think the sliding friction explanation is the answer?

    Does anyone know the coefficient of friction between cue ball and tip?

    Thanks. I'm not make a billiard game, just curious what is the case in real-world situation. Can confirm that the tip-ball COF listed on Dr.Dave's webpage is for a chalked tip and the ball, NOT bare tip.

    Does anyone know the coefficient of friction between cue ball and tip?

    No, and I don't intend to improve my skill by knowing it to begin with. You don't care doesn't mean no one cares.

    Yeah, checking for direction of ball motion might be a better idea

    Does anyone know the coefficient of friction between cue ball and tip?

    So I'm still thinking about the miscue limit mentioned by Dr.Dave, and I'm wondering if anyone knows the COF (static and sliding) between the cue ball and a leather tip (chalked and no-chalk)? If not, I'll do an experiement myself and report up here.

    If @nataddrho hasn't thought of this already, here is my thought on reporting miscue. If a miscue happens, the angular speed of the ball will be much less than the one predicted by physics. You can see Dr.Dave article https://billiards.colostate.edu/technical_proofs/new/TP_A-30.pdf Since...

    About those Chinese 8-ball tables

    To my understanding the pockets are supposed to be the same as snooker pockets. I know that they can be as tight as 82mm. As comparison, the 4 1/4 inch pockets on American pool table is 108mm wide

    Premium Chalks – Are They Worth It?

    So I understand that when the shot is good, there's no sliding involved, hence no sliding friction. But when miscue happens, the tip slides, right? It seems that the two situations are very different.

    Premium Chalks – Are They Worth It?

    I don't know about Dr.Dave's reputations among students, but from all the interactions I had with him, he's great. Also, there's a survivorship bias on websites like "rate my professors" since most students don't rate their professors, just like you won't likely rate a good restaurant, but you...

    Premium Chalks – Are They Worth It?

    Right, but on the other hand, it seems that increase in friction doesn't help at all. I remember Dr.Dave said that from observations it seemed any increase in friction at this point doesn't prevent a miscue. So the reason might not be as simple as what I guessed.

    Yes, that's a better way to put it.

    Premium Chalks – Are They Worth It?

    Here is a possible explanation for why the miscue limit is half the radius: I wonder if it is simply because the coefficient of friction between chalk and the ball is very close to 0.5? Since the miscue limit is half the radius, this means the cue line makes an angle of 60 degrees with the...

    Reason for “expensive “ chalk

    Got it. Skid is a rare event in all cases, but I feel like Taom brings it down to pracatically non-exsistent.

    Reason for “expensive “ chalk

    really? I've only played pool for 5 or so years and if I use Masters I get kicks. Not often, but I do get kicks.
