Earth moment of inertia

WebApr 14, 2024 · Since we know so many properties of the Earth so well, like its mass and its moment of inertia, we can turn this knowledge around to use seismic data to constrain modified gravity theories. Web1. You have to use the moment of inertia of the spherical shells in your derivation, which is. d I = 2 3 r 2 d m = 2 3 r 2 d ( 4 π r 2 d r) Integrating this will give the correct answer. Remember, you're adding up the spherical shells, not individual point masses, so this changes the calculation. Share.
