            The rotational kinetic energy of the mass in Figure 3.2.1 is given by

                                                                       (3.2.6)

            where the moment of inertia is


                                                                       (3.2.7)


            with ρ(r) the mass distribution at radius r in a volume. In the simple case
            shown where m is a point mass, this becomes
