Mass moment of inertia is calculated by multiplying an object's center of mass by the square of the distance to its axis of rotation. If that sounds a lot like torque, that's because it is.

Moment of inertia is different than mass, but I like to call it the "rotational mass". What does mass do? Things with larger mass are more difficult to change their motion (translational motion).

The area moment of inertia (also called the second moment of area) defines the resistance of a cross-section to bending, due to the shape of the cross-section. It is a key parameter for the ...

On Aug. 30, 2005, the USGA published a proposal to implement a test and limit for clubhead moment of inertia (MOI). The USGA Equipment Standards Committee received detailed written comments from ...
