Question: In rotational dynamics, what does the moment of inertia depend on?

Options:

Correct Answer: Mass and shape of the object

Solution:

The moment of inertia depends on both the mass distribution and the shape of the object relative to the axis of rotation.

Moment of Inertia – The moment of inertia is a measure of an object's resistance to changes in its rotational motion, depending on how its mass is distributed relative to the axis of rotation.
Mass Distribution – The arrangement of mass within an object affects its moment of inertia; mass further from the axis contributes more significantly.
Axis of Rotation – The choice of axis around which the object rotates is crucial, as the moment of inertia can vary for the same object depending on this axis.
