# Central force field

## 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?
thank you

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!!
