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.
Conceptually, moment of inertia can be thought of as representing the object's resistance to change in angular velocity, in a similar way to how mass represents a resistance to the change in velocity in non-rotational motion, under Newton's laws of motion.
