what is moment of inertia in golf clubs
Updated January 03, 2017. The acronym MOI stands for moment of inertia, and in golf MOI is a measurement of a club's resistance to twisting. The term is usually applied to clubheads, but can also be applied to golf balls and even shafts. In layman's terms, a higher-MOI golf club will be more forgiving than a lower-MOI club.

It is always considered with respect to a reference axis and how that cross-sectional area is distributed about the reference axis, usually a centroidal axis.
