Discuss the generalization of Kepler second law briefly.
The second law of Kepler states that the line joining the bodies sweeps out equal areas in their orbits in equal intervals of time.
Newton showed that this generalized law is a consequence of the conservation of the angular momentum of an isolated system of two bodies unperturbed by other forces.
Now consider the following small wedge of the orbit traced out in time dt,
