The concept of moment of inertia is critical in understanding how objects respond to applied torques. An object with a high moment of inertia has a greater tendency to resist changes in its rotational motion due to its mass distribution relative to the axis of rotation.

When torque is applied to such an object, it requires a greater amount of torque to achieve a change in its angular velocity compared to an object with a lower moment of inertia. This resistance is a result of the object's mass being distributed farther from the axis of rotation, making it more stable in its current rotational state.

This makes the scenario where the object resists changes in its state of rotational motion consistent with the principles of rotational dynamics. Therefore, when a torque is applied, the object with a high moment of inertia does not easily accelerate or decelerate its rotation, thus exhibiting resistance to changing its state.
