Mariam Cisneros · Answer 1

It is within the definition of moment of inertia itself that rotational inertia appears. Just like some people interpret an object's mass as a resistance to changes in its linear motion, some people interpret an object's moment of inertia (around a given axis) to be its resistance to changes in its rotational motion around that axis.
