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.
The mechanics of the Earthâs rotation avout its axis introduces a quantity called the moment of inertia, which is the rotational mechanical analogue of mass. The moment of inertia of a point mass, m, rotating at a distance, r, about an axis is mr 2.
