The moment of inertia of a point mass is often stated, without any justification, as being the mass of the particle \(m\) multiplied by the square of its distance \(k\) from the axis of rotation, or \(mk^2\). It is the rotational equivalent of inertia or mass in systems involving linear acceleration. The ‘moment of inertia’ of a rotating body is the body's resistance to angular acceleration.

Borgel 2: Taubert & Fils and Taubert Frères.Borgel 1: François Borgel and Louisa Borgel KCET 2009: The moment of inertia of a circular ring of radius r and mass M about diameter is (A) (Mr2/4) (B) (Mr2/2) (C) (Mr2/12) (D) (2/5)Mr2.Considering its two diameters that are perpendicular to the axis. For finding moment of inertia around its diameter, you have to use perpendicular axis theorem. Moment of inertia of a circular wire about its axis is MR 2.
