The Radius of Gyration
The root mean square distance of its constituent particles from the axis of rotation is called the radius of gyration of a body.
It is denoted by K.
Radius of gyration
CBSE Class 11 Physics Notes Rotational Motion
The product of the mass of the body (M) and square of its radius gyration (K) gives the same moment of inertia of the body about rotational axis.
Therefore, moment of inertia I = MK2 ⇒ K = √1/M
