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. It is the ratio between the torque applied and the resulting angular acceleration about that axis.
Mass Moment of Inertia (Moment of Inertia) - I - is a measure of an object's resistance to change in rotation direction. Moment of Inertia has the same relationship to angular acceleration as mass has to linear acceleration.
Basically: Mass moment of inertia is an object’s resistance to rotation and is impacted by mass and distance from the axis of rotation. Application : The speed that something rotates, such as a satellite spinning in space, is impacted by it’s inertia.

Application: The speed that something rotates, such as a satellite spinning in space, is impacted by it’s inertia. A bigger inertia has a smaller angular acceleration.
The mass moment of inertia is often also known as the rotational inertia, and sometimes as the angular mass. For simple objects with geometric symmetry, one can often determine the moment of inertia in an exact closed-form expression.
In this subsection, we show how to calculate the moment of inertia for several standard types of objects, as well as how to use known moments of inertia to find the moment of inertia for a shifted axis or for a compound object.
21 wrz 2021 · Here, the \(I\) represents the mass moment of inertia, which is the three-dimensional measure of a rigid body’s resistance to rotation around an axis. Mass moment of inertia plays the same role for angular motion as mass does for linear motion.
