Central Force Field: Meaning of Centrifugal Term

[rob60]

Homework Statement

In the study of motion in a Central-Force Field in radial coordinates it is defined an effective potential energy which depends only on the radius r: in particular there is a term 'centrifugal' because the relative force (-grad) has a centrifugal versus. What is the meaning of this expression since it is derived from an inertial frame?

What is a centrifugal versus?

And I don't think you should be using the term centrifugal anyway! The is no such thing as a centrifugal force!

oh yes. My english is inadequate: excuse me, please.
the 'effective potential expression' has a term: + L^2/(2mr^2).
The force associate is directed outward from the center of the orbit, it looks like a 'centrifugal force'.
