According to Wikipedia:

Radius of gyration or gyradius of a body about an axis of rotation is defined as the radial distance of a point, from the axis of rotation at which, if whole mass of the body is assumed to be concentrated, its moment of inertia about the given axis would be the same as with its actual distribution of mass.

This to me seems very similar to the concept of the center of mass, a point in space where we can assume all the mass of the object is concentrated at, and can be treated as particle.

Is this true? Can these be thought of as similar concepts defined in rotational physics?

P.S: sorry for any bad English, thanks!
