In physics, the
moment of force (often just
moment, though there are other quantities of that name such as moment of inertia) is a quantity that represents the magnitude of force applied to a rotational system at a distance from the axis of rotation.
The concept of the moment arm, this characteristic distance, is key to the operation of the lever, pulley, gear, and most other simple machines capable of generating mechanical advantage.

I would really like to understand how this 'moment arm' works and is applied in the golf swing. Can anybody explain ?
