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.

What is the rotational analog of mass in linear motion?
That is called moment of inertia.
Physical quantity coressponding to inertia is rotational motion?
The physical quantity for rotations corresponding to inertia is the moment of inertia, or rotational inertia. It is represented by the integral of r^2dm.
What physical characteristic does the moment of inertia of a rotating object most directly and accurately measure?
This is rotational inertia. When inertia forces an object to rotate, it will continue to do so until another force acts upon it.
The rotational inertia of an object increase as the mass and the distance of the mass from the center of rotation?
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.
The product of an object's rotational inertia and its rotational velocity is?
The object's angular momentum

What is rotational inertia?
Rotational inertia is sometimes called spin. It involves the movement of a mass around an axis. This moving mass will have some measure of kinetic energy that is due to the fact that it is spinning. The variables are the shape and the mass of the object, the way the mass is distributed within the object, the speed of its rotation, and the location of the axis of spin through the object. The moment of inertia might also be called angular mass, mass moment of inertia, rotational inertia, or polar moment of inertia of mass. Use the link below for more information.
Physical quantity coressponding to inertia is rotational motion?
The physical quantity for rotations corresponding to inertia is the moment of inertia, or rotational inertia. It is represented by the integral of r^2dm.
Why moment of inertia is also called rotational inertia?
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.
What is the property of an object that resists changes in rotational motion?
rotational inertiaMass moment if inertia.
What is meant by moment of inertia in Induction motors?
The second moment of a force is called as moment of inertia.
Is rotational inertia enhanced with long legs?
Yes, having long legs can enhance rotational inertia because the mass of the legs is distributed further from the axis of rotation, increasing the moment of inertia. This can provide more stability and control in activities that involve rotation, such as gymnastics or diving.
What physical characteristic does the moment of inertia of a rotating object most directly and accurately measure?
This is rotational inertia. When inertia forces an object to rotate, it will continue to do so until another force acts upon it.
Relation between stress and moment of inertia?
is a resisstance of a body is called inertia
What is rotational analog?
The rotational analog is 2nd of newtons law it is the angular acceleration of a rigid object around an axis is proportional to the next external torque on the body around its axis and inversely proportional to the moment of rotational inertia about that axis.
Is angular acceleration proportional or inversely proportional to torque?
Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).
