The "orbits" in this case have no closed-form in terms of circular or elliptic functions. The locus of the body will tend to fill space in an annular region around the central point. This image of a $F=-1/r$ orbit was produced by "central force workbench" by Juan M. Aguirregabiria. The potential is now of the form $V= \ln|r|$. The only ...

You can say that if a object has kinetic energy in the vicinity of a massive object it has potential energy. And if the angle bitwext the radial vector and velocity vector Is not 0 or 180 secs The object has angular momentum And a path with angular momentum Is curved. Light has kinetic energy so it can be bent by Newtonian gravity. In fact I can’t swing by a ...
