Moment of inertia - Wikipedia
The moment of inertia, otherwise known as the mass moment of inertia, angular/rotational mass, second moment of mass, or most accurately, rotational inertia, of a rigid body is defined relative to a rotational axis.
Moment of Inertia: Definition, Formula, Examples, & Table
Aug 2, 2023 · Moment of inertia, also known as rotational inertia or angular mass, is a physical quantity that resists a rigid body’s rotational motion. It is analogous to mass in translational motion . It determines the torque required to rotate an object by a given angular acceleration .
