Moment of Inertia
1 articleMoment of inertia describes a body's resistance to angular acceleration about a specified axis, and in golf it helps characterize how a clubhead responds to off-center impact. A higher value about one axis does not imply all forms of forgiveness are identical. Discussion should identify the axis and measurement context, keeping MOI separate from center of gravity location and face-flex measurements.
