Moment of inertia is a measure of an object's resistance to changes in its rotational motion. It depends on both the mass of the object and how that mass is distributed around the axis of rotation.

Common units of measurement related to moment of inertia include kilogram square meters (kg·m²) and gram square centimeters (g·cm²).

• Moment of inertia is crucial in determining how objects will rotate around a given axis.
• It is essential in engineering and physics for analyzing the stability and dynamics of rotating systems.
• Helps in designing machines and structures to ensure they operate efficiently and safely.
