I have a small psi wheel, which when tried found that it rotate more fast
than large ones. It may be because, since size of the wheel is less
it's moment of inertia (I) is low. Since twisting force is same
the angular velocity increase
According to conservation of angular momentum, If there is no
external torque acting on a system, total angular momentum remains
constant.
Angular momentum = Moment of inertia x Angular velocity
