Since gravitational field is conservative, we can conserve the total mechanical energy of the system of interacting particles. As the net force acting on a closed system is zero, we can conserve the linear momentum of the system. Since the gravitational forces between two interacting particles are actionreaction pair, the net torque experience by the system about any inertial point is zero. Hence, angular momentum of the system remains constant about any inertial point. A body of massm ( < < M )
