Is rotational inertia an intrinsic property of an object?

Homework Statement

Is rotational inertia an intrinsic property of an object?[/B]

Homework Equations

The Attempt at a Solution

So I know that rotational inertia is a property of an object that deals with a resistance to a change in the state of rotational motion but is it an intrinsic property? I wouldn't have thought that it was intrinsic because it deals with something that changes outside of any object.
any help is appreciated. [/B]

Look up the definition, e.g. https://en.m.wikipedia.org/wiki/Intrinsic_and_extrinsic_properties

i don't understand what you mean? i know what intrinsic means

is it intrinsic because its the object itself that has the rotational inertia ?

No, it seems you do not understand the meanings of intrinsic and extrinsic in physics.
The density of a material is an intrinsic property; the mass of an object made of the material is an extrinsic property.
Read the link I posted.

Basically they are asking if the moment of inertia of an object is an intrinsic property of an object. Read the link haruspex posted and decide if the moment of inertia of an object is an intrinsic property or not.

so i have read that article and i understand that an intrinsic property is a property that isn't changed and is there no matter the amount of material or if it is a different piece or only part of an object like density, so i don't think that rotational inertia is an intrinsic property, i don't see how it could be?

That's right. It is an extrinsic property, because it is a property of the body as a whole, not a property possessed by every part of the body independently.
