The tendency of a body to resist angular acceleration WordNet 3.0
The moment of inertia, otherwise known as the mass moment of inertia, angular mass or rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis; similar to how mass determines the force needed for a desired acceleration. Wikipedia
Also known as Rotational Inertia, is the tendency of a body to maintain its state of rest or uniform rotation unless acted upon by an external torque. This is the rotational physics equivalent of the inertia in linear physics. Wikipedia Disambiguation
Scalar measure of the rotational inertia with respect to a fixed axis of rotation Wikidata
A measure of a body's resistance to bending; second moment of inertia; second moment of area. Wiktionary
