Rotational Motion & Angular Momentum

Moment of Inertia vs. Angular Momentum Any moving body has inertia. (It wants to keep moving at constant v.) The more inertia a body has, the harder it is to change its linear motion. Rotating bodies possess a rotational inertia called the moment of inertia, I. The more rotational inertia a body has, the harder it is change its rotation.

Moment of Inertia in Golf Clubs

MOI (Moment of Inertia) It will be easier to understand MOI if you think of it as an MOF (Measure of Forgiveness). Moment of Inertia is a measure of a body's resistance to angular acceleration (twisting). In golf, MOI comes most into play on imperfect contact, when the ball and the clubface meet someplace other than the sweet spot.

Swing Weight: Why moment-of-inertia matters more than weight

Sep 04, 2008· The bat rotates from being essentially parallel to the ball's path to being perpendicular to the ball's path at the moment of impact. During this part of the swing, when the bat is primarily rotating about a point near the player's wrists, the actual weight of the bat is less important than the swing weight (moment-of-inertia).
