Acroterion, thanks for your reply. Yes I am totally outnumbered as regards a key point. I don't believe that the rotating frame of reference transformation equations can be applied to non-rotating situations.  ::But the edit war on the main page has not been about that issue recently.  ::I very carefully chose an example of centrifugal force that would actually be covered by those equations. I did that deliberately in order to totally remove any possible excuse that they might have to delete it, although I fully expected that Wolfkeeper would delete it anyway because he deletes my edits systematically.  ::I wanted you to look at the pathetic excuses that they were giving to justify Wolfkeeper's actions.  ::As you can see, Itub has been denying that a centrifugal force is involved in the outward radial acceleration of the marble along the groove.  ::It is that kind of blatantly dishonest denial that I wanted an administrator to look at.  ::Basically they are covering up for wikistalking on the part of Wolfkeeper.  ::You can see my latest reply to Itub on the talk pages of centrifugal force.
