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.
Objects with uniform density have moments of inertia of the form ! I = k (mr 2) where k is a constant specific to the geometry of the object and the location of the rotation axis, m is the mass, and r describes certain dimensions of the object (not necessarily a radius). Dimensional analysis of the moment of inertia expression tells us that it has units of kg-m 2.
