I'm learning how to find these things in school but I have no idea what they are. Moment of inertia's units are distance^4 such as in^4 or mm^4. Mass moment of inertia has units of mass*distance^2 such as kgmm^2. Radius of gyration is a distance such as mm or in.
So what are they exactly and how are they used.
