Which of the following is not correct when describing moment of inertia?
distribution of mass
resistance to rotational motion (spin)
shape of object doesn't matter
calculated as a constant times "mR2"
The moment of Inertia is understood as the rotational analogue of the mass of the body.
As the mass of a translating object defines its inertia, which is defined as the resistance of a body to resist any change in its present state of either rest or motion.
In a similar way moment of inertia of a rotating object is defined as the resistance to change in its angular motion.
In the problem mentioned above.
The option A is related to the moment of inertia of any rotating object. For example, The moment of inertia of two circular objects, a ring a...
