## Main Question or Discussion Point

In CM there is this equation of motion for ciruclar orbits:

F=k/r^2=m*v^2/r, where k depends on the force involved.

I know this gets complicated in GR, but is there a simple expression for circular orbits in SR, what happends to the m*v^2/r ?

If the forces are only electromagnetic, does k/r^2 change in SR ?

Also, is the quantity L=mrv conserved in SR, or some modification ?
