ABSTRACT
The familiar double-pendulum model of the golf swing was applied to the downswing and follow-through swing planes of low handicap golfers. Coplanar swings were predicted in which downswing and follow-through clubhead displacements follow the same plane. It was found that centrifugal forces generated by the pendulum action are used by better players to keep the clubhead on plane. Furthermore, centrifugal force, rather than supination of the left wrist, provides the mechanism to square the clubface at impact. The clubhead was found to rotate about a central pivot.
