"WebThe precession angular velocity is ωP = dφ dt ω P = d φ d t and from this equation we see that ωP = rMg L. or, sinceL= I ω, ω P = r M g L. or, since L = I ω, ωP = rMg Iω. ω P = r M g I ω. In this derivation, we assumed that ωP ≪ ω, ω P ≪ ω, that is, that the precession angular velocity is much less than the angular velocity of the gyroscope disk. " - Spin angular velocity
