This demonstrates a planar trajectory in a central field represented by a potential of the form

V(r)=α

. Motion in a central field is one of the classical problems of classical mechanics. Many interesting phenomena are exhibited by the motion of a small mass in a central field, like Bertrand's theorem, the fall into the center for strongly singular potentials, ….
