Question

The moment of inertia of a body is does not depends up on

• A. shape of the body
• B. mass of the body and its distribution within the body
• C. angular velocity of the body
• D. axis of rotation of the body

Answer 1

Answer:

C. angular velocity of the body

moment of inertia is a property of mass distribution and axis of rotation. it depends on the shape and size of the body as the distance from the axis changes . the equation for point mass moment of inertia is $I=m\times r^2$ . it does not depend on the angular velocity of the body.
