Web29 sep. 2024 · September 29, 2024 by George Jackson. Rotational inertia is a scalar, not a vector and is dependent upon the radius of rotation according to the formula rotational inertia = mass x radius^2. Rotational inertia, rotational inertia is the measure of an object’s resistance to change in its rotation. Table of Contents show. Web28 dec. 2024 · The principle of inertia describes the tendency of an object to remain in a state of rest or remain in motion at a constant velocity. It is thus a measure of an object's resistance to changing its state, be it a moving body or something sitting on a table.
