Do 45 RPM records need higher anti-skate setting?

Dear Omsed,
The question was around the two terms "centrifugal" and "centripetal". I was pointing out that in Newtonian terms there is no such thing as centrifugal force, that the force holding a body in circular orbit around an origin is centripetal (center-seeking, not center-fleeing). I cannot recall my exact words, nor do I wish to search for them, but I had no intention of implying that there is centripetal force involved in skating, if that's what you mean here.

I still would like a clue about your credentials in the audio/engineering business, just because you sound like an interesting and experienced person from whom we can learn.

Oh yes, it was you to whom I was responding, Omsed. It was you who used the term "centrifugal". So what's your point? I did find my response, and I don't see where I ever said anything that could be construed as attributing skating to a centripetal force. Indeed, as noted above, I was just discussing the physics of a body in orbit.

Misunderstanding: it was the blog about anti-skate that an above poster referenced which mentioned centripetal force, which makes the science credentials of the blogger suspect.

Omsed,
You need to read and assimilate before spouting. Otherwise you may be
considered a wanker.

So would you care to enlighten us otherwise why anyone would use 45 rather
than 33 1/3 other than to be able to have a disc with higher modulation?
As far as my (possibly inferior) knowledge is aware, that a body revolving
faster has more energy than one revolving slower. I thought this was
something to do with kinetic energy?
Therefore permitting higher signal levels to the cartridge.
Of course you may not have noticed any difference between 45s and 33s, in
which case get yourself some and listen....

Re centipetal force - think about it. The only revolving item other than the
platter, is the tonearm, which is the item under discussion, and there are
minimal, and irrelevant, centripetal forces acting on it, which is what I have
said in the blog.

Omsed, Point taken. Sorry.

John, The tonearm is stationary, resisting the force of friction on the stylus tip which would tend to want to pull the tonearm clockwise in the direction of LP rotation. But I have privately wondered about a tiny centripetal force exerted by the LP on the stylus tip, as the grooves spiral inward. I think it's overcome or negated by the skating force.
