The moment of inertia I is also defined as the ratio of the net L of a system to its ω around a principal axis, that is If the angular momentum of a system is constant, then as the moment of inertia gets smaller, the angular velocity must increase.
Radius of Gyration Radius gyration can be said as the perpendicular distance from the axis to the point at which the whole mass of the body is to be assumed to be concentrated at that point only.
This point also corresponds to the.
