Moment of inertia, often denoted by \\( I \\), is a physical quantity that measures how much an object resists rotational motion about a specific axis. It plays a similar role in rotational dynamics as mass does in linear dynamics. The moment of inertia depends on the mass distribution of an object relative to the axis of rotation.
