The moment of inertia is a value that measures how difficult it is to change the state of an object's rotation. The moment of inertia depends on the mass and shape of an object, and the axis around which it rotates. The moments of inertia for some common shapes can be found using the...
It can be found by integrating over the mass of all parts of the object and their distances to the center of rotation, but it is also possible to look up the moments of inertia for common shapes. The angular momentum is the product of the moment of inertia and the angular velocity ...

The Mass Moment of Inertia of a solid measures the solid's ability to resist changes in rotational speed about a specific axis. The larger the Mass Moment of Inertia the smaller the angular acceleration about that axis for a given torque. The mass moment of inertia depends on a reference ...
