EARTH'S MASS, DENSITY, AND MOMENT OF INERTIA. To learn what the earth is made of, our first constraint is its density (mass / volume). We find its mass from the acceleration of gravity g. The universal law of gravity says that the force F betwen objects M and m.
One might think that the total moment of inertia would just be the mass of the sphere times the distance from the center of mass to the axis of rotation squared. So the moment of inertia would be 9MR 2. However, if you checked this out experimentally, you d find that this value is too low.
