Any kind of moment of inertia is basically a measure of an objects resistance to a change in its state of motion.
Mass moment of inertia is a measure of the resistance offered by a body to a change in its angular momentum. Conversely one can also say, it is the change in angular momentum produced by a unit change in angular velocity (ω).
Area moment of inertia is a measure of the flexural stiffness of a beam. It is in essence a measure of the resistance offered by a beam to bending deflections. It is material independent, so you can say it is the capacity of a cross-section to resist applied bending.
The difference between area moment of inertia and mass moment of inertia is with respect to measurement and motion.
In structural engineering, the total area moment of inertia is a property which is used to determine an object's resistance to bending.
It is frequently employed in calculations relating to deflection, bending stress, and stability of beams and columns since it quantifies the distribution of an object's area about an axis.
Thus, the object is generally more resistant to bending the larger the area moment of inertia.
The ability of an item to resist changes in rotational motion is measured by its mass moment of inertia, a quality utilised in both physics and engineering.
Calculations about rotational dynamics and angular acceleration use it to quantify mass distribution of rotational axis. An object's resistance to changes in rotational motion increases with increasing mass moment of inertia.
