Important in determining a system's rotational motion, FTP, identify this physics quantity that is considered the rotational analog of mass and is generally designated I.
When one accounts for the mass distribution, it can be found by using the parallel and perpendicular axis theorems.  It is the common factor in rotational kinetic energy and angular momentum, and when multiplied by the angular acceleration, this quantity yields the net torque in a system.
