Moment of inertia is also known as the rotational inertia. When masses are in linear motion, its rotational analog is known as rotational inertia. The moment of inertia provides the relationship for dynamics of rotational motion. The moment of inertia can be calculated with respect to the axis of rotation of the particles.
Thus, moment of inertia in other terms is known as the mass distribution of the particle with respect to the axis of rotation. The distribution of the particle from the axis of rotation is also dependent on the shape and size of the object. Thus, the moment of inertia of the object depends on the mass, axis of rotation and shape and size of the body.
