Hi ManDay!

(btw, "helically" means like a spring … did you mean like a sort-of sine function?)

If the only force is radial, then good ol' Newton's second law means that the particle will have no reason to turn, and so will move along a great circle ("an equator").

The radial force may change the

Like a spring, yes.

Since this is the physics-forum I assume you can assume that everyone can presume at least a basic knowledge. Know about that "newton-stuff" :D I'm concerning the mathematical aspects since this is the maths-subsection. I was asking for a sort of special topology or reference-space in this would be possible.

Mathematically, you can't have a spring on the surface of a sphere, or "constrained to equal distance to the surface".

Changing the coordinates won't alter this basic reality.
