For ten points, identify this rotational analog of mass with SI units of kilograms times meters squared, often symbolized capital I.
When a rigid object is stretched parallel to its axis of rotation, this quantity is unchanged according to the Stretch Rule. Its scalar form is proportional to the square of the radius of gyration, and it is also equal to the torque over the angular acceleration. The rotational kinetic energy equals one half times the square of the angular velocity times this quantity, which can be found via the parallel axis theorem. For ten points, identify this rotational analog of mass with SI units of kilograms times meters squared, often symbolized capital I.
