But any talk about cause and effect, action-reaction, is a red herring.
When you whirl a stone attached to a string above your head, the
changes in velocity are directed towards the center of the rotation and
it is the centripetal acceleration. But we canniot answer whether it is
the rotation of the stone that causes the centripetal acceleration or
the centripetal acceleration that causes the rotation when we are in
uniform motion. Sames about action-reaction talk. We cannot know what
is the REAL action.

OK, but standard nomeclature in physics is to use the
term 'centrifugal force' only for the inertia force that it
is necessary to invoke if you wish to use
Newton's laws, unchanged, in a rotating reference
frame.

The centrifugally directed reaction force of the stone
on the string in not normally referred to as centrifugal
force.

It is curious that relativists try to deny causality by talking about
causality all the time and more importantly deny causality by having a
preferential view of what causes what.

Explain please.
