The rotational inertia of an object depends upon the distribution of:
AMass within the object
BCharge on the surface
CHeat through the body
DLight across the face
Answer & Solution
Correct answer: A. Mass within the object
1. Rotational inertia is not just about how much mass there is.
2. Two objects of equal mass can resist rotation differently.
3. The rotational inertia of an object or system depends upon a distribution.
4. It depends upon the distribution of mass within the object or system.
