Is rotational inertia an intrinsic property of an object?

Click For Summary

Homework Help Overview

The discussion revolves around the nature of rotational inertia and whether it is considered an intrinsic property of an object. Participants explore the definitions of intrinsic and extrinsic properties in the context of physics, particularly focusing on how rotational inertia relates to these concepts.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants question the definition of intrinsic properties and how it applies to rotational inertia. Some express confusion about the relationship between an object's properties and its rotational inertia, while others attempt to clarify the distinction between intrinsic and extrinsic properties.

Discussion Status

The discussion is active, with participants sharing their interpretations and seeking clarification on the definitions involved. Some have referenced external resources to aid understanding, and there appears to be a mix of interpretations regarding whether rotational inertia is intrinsic or extrinsic.

Contextual Notes

Participants are referencing definitions from external sources to clarify their understanding of intrinsic and extrinsic properties, indicating a need for deeper exploration of these concepts in relation to rotational inertia.

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

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.
