Motion under this type of force is known as Keplerian motion, and forces of this type include the two most familiar, the electrostatic force between two charges and the gravitational force between two masses.
The quantity conserved in motion under this type of force is known as the Runge-Lenz vector, and Bertrand's theorem states that the only types of forces that produce stable orbits are linear (spring-like) forces and this type of force. Motion under this type of force is known as Keplerian motion, and forces of this type include the two most familiar, the electrostatic force between two charges and the gravitational force between two masses. FTP what is this type of force proportional to 1 over the square of the distance?
