Mass and radius
Yes, rotational inertia is the same as moment of inertia. Both terms refer to the resistance of an object to changes in its rotational motion.
Rotational inertia depends on the mass of the object and how that mass is distributed around the axis of rotation. It is also influenced by the shape and size of the object.
Moment of inertia and rotational inertia are essentially the same concept, referring to an object's resistance to changes in its rotational motion. Moment of inertia is the term commonly used in physics, while rotational inertia is a more general term that can also be used. In the context of rotational motion, both terms describe how the mass distribution of an object affects its ability to rotate. The moment of inertia or rotational inertia of an object depends on its mass and how that mass is distributed around its axis of rotation. In summary, moment of inertia and rotational inertia are interchangeable terms that describe the same physical property of an object in rotational motion.
The physical quantity corresponding to inertia in rotational motion is moment of inertia. Moment of inertia is a measure of an object's resistance to changes in its rotational motion. It depends on both the mass and distribution of mass in an object.
That's what it's all about: about rotation. The "inertia" part is because it is comparable to the linear inertia: that's what makes it difficult to change an object's rotation.

Rotational inertia and moment of inertia are terms used interchangeably in physics to describe an object's resistance to changes in its rotational motion. Rotational inertia specifically refers to an object's resistance to changes in its rotational speed, while moment of inertia refers to an object's resistance to changes in its rotational motion due to its mass distribution. In essence, moment of inertia is a more specific term that quantifies rotational inertia. Both concepts are crucial in understanding how objects move and rotate in the context of physics.
The relationship between disk rotational inertia and the speed at which a disk spins is that the rotational inertia of a disk affects how quickly it can change its speed when a torque is applied. A disk with higher rotational inertia will spin more slowly for a given torque, while a disk with lower rotational inertia will spin faster for the same torque.
The mass, and how it is distributed- how far the masses are on average from the axis of rotation. However, it is the square of the distance that counts in this case.
The moment of inertia is a measure of an object's resistance to changes in its rotational motion. In the context of rotational dynamics, the moment of inertia list is significant because it helps determine how an object will respond to external forces and torques, influencing its rotational acceleration and stability.

Answer #1:The Rotational Inertia of an object increases as the mass "increases" and thedistance of the mass from the center of rotation "decreases".=================================Answer #2:If Answer #1 were correct, then flywheels would be made as small as possible,and a marble would be harder to spin than a wagon wheel is.An object's rotational inertia (moment of inertia) increases in direct proportionto its mass, and increases in proportion to the square of the distance of themass from the center of rotation.
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.
