The mass of Jupitar … WebFor now, we leave the expression in summation form, representing the moment of inertia of a system of point particles rotating about a fixed axis. We note that the moment of inertia of a single point particle about a fixed axis is simply [latex]m{r}^{2}[/latex], with r being the distance from the point particle to the axis of rotation. In the ...
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.

WebJan 25, 2024 · 1. The moment of inertia is a measure of how a mass of a rotating body is distributed about the axis of rotation, and its symbol is I. The angular momentum is the mass times the cross product of the vectors r and v, or the product of the moment of inertia and the angular velocity ω. Its symbol is L.
