Sorry. I will read.

But given that we are talking about Centripital Force (cf) Centrifugal
Force (cf) and Coriolis Force (cf) can we stop with the initial? G

Seriously though, it is one case where it might be an idea.

No.. Sorry. I had read it already. How does it remove centrifugal
force? It actually describes it as a "useful concept" To me
centripital force is the force that stops me moving. I in turn exert a
force on the thing that stops me moving. _What's that force_?

force.

And what holds the string straight?
