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.
The object's angular momentum
Mass and radius
Center of gravity = center of mass, for most practical purposes. Mainly, the center of mass is the place where you imagine the mass to be concentrated. However, as a result, you can also consider inertia and weight to be concentrated at the center of mass.
Calculating system inertia by mutiplying the Inertia Time Costant [Sgn] of every single generator to calculate the inertia of the generator and sum all inertias to calculate the whole system inertia Calculating system inertia from the RoCoF (post fault calculation)
No. For the rotational inertia, the distribution of masses is relevant. Mass further from the axis of rotation contributes more to the rotational inertial than mass that is closer to it.
The bike wheel. It wil have its mass concentrated out by the rim.

Stright
That is called moment of inertia.
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 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.
