NettetAnswer (1 of 3): Obviously the moment of inertia about an axis through the sphere’s center depends on both the mass and the radius of the sphere. So I’m assuming you are comparing two sphere’s with the same masses and radii. But the moment of inertia also depends on how the mass is distributed. T...
