This is a normal post I thought centrifugal force didn't exist?
We were always taught it was centripetal acceleration acting on a mass, and the reaction in the string gives an apparent force.
Probably why he kept referring to it as 'so-called' centrifugal force.

This is a normal post It emerges
when you use a rotating frame of reference.

Which is a (possibly) clever thing to say that I don't really understand, but stole from XKCD...

This is a normal post The point is this phantom force feels real enough when it's smearing the fine paste that used to be you evenly across the inside edge of a centrifuge.

It depends on your frame of reference I believe. If the FoR is rotating with the system, then the force is centrifugal. If the FoR is an inertial one, it's centripetal.
Edit: Yeah, essentially what FB's xkcd link says. Should probably refresh before commenting next time.
