Mass
Increasing the mass of an object will increase its inertia. Also, increasing the speed at which an object is spinning will increase its rotational inertia. Additionally, increasing the distance of an object from the axis of rotation will increase its rotational inertia.
Since its length is doubled, the number of molecules present increase, resulting in an increase in mass of the rod. And we all know that mass is directly proportional to inertia, therefore the moment of inertia also increases.
This is an example of inertia, the tendency of an object in motion to stay in motion. As you increase your velocity on a skateboard, your momentum also increases, making it harder to stop because of this inertia.
The moment of inertia of the compact disk will increase by a factor of 4 (2 raised to the power of 2) when its diameter is doubled while maintaining the same thickness. This is because moment of inertia is proportional to the square of the radius.
When you increase your velocity on a skateboard it is harder to stop because of momentum.

Increase the moment of inertia
A rotating body that spins about an external or internal axis (either fixed or unfixed) increase the moment of inertia.
Decrease mass, thereby decreasing inertia in the system, or increase power, thereby overcoming the effect of the inertia.
If the mass is larger, the inertia is larger as well. Inertia is the property of an object that resists changes in its state of motion, and it is directly proportional to mass. Therefore, an increase in mass results in an increase in inertia, making it more difficult to change the object's motion.
Force applied to the object

Because it is a measure of the "resistence" of an object to be accelerated in its rotation. An object with a big moment of inertia is more difficult to increase/decrease its angular velocity (speed of rotation), than an object with a low moment of inertia.
