Oh, so the ball starts at the waist of the inside of the sphere, and then rolls down and back up, kind of like a modified pendulum. Got it. As jasc15 points out, the main difference for this system versus a pendulum is the energy that goes into the rolling ... WebMoment of Inertia (I) = Σ miri2 where, m = Sum of the product of the mass. r = Distance from the axis of the rotation. And the Integral form of MOI is as follows: I = ∫ d I = ∫0M r2 dm where, dm = The mass of an infinitesimally … bitcoin to the pound
