. . . what's the line on "centrifugal force" again . . .

Homer Kelley told me 27 years ago that Centrifugal Force had been defined by scientists as a 'ficticious force'. Nevertheless, he chose to use the term as he himself defined it ("The resistance of the inertia in an orbiting object to change in direction." / The Glossary) in his three-piece solution to the three-dimensional puzzle of G.O.L.F.:

1. Centrifugal Force (Clubhead Control);

2. The Inclined Plane (Clubshaft Control); and

3. Hinge Action (Clubface Control).

As long as Newton's First Law (God's Law) of Motion stands, so does Homer's definition.

For those who persist in the academic conception, get over it.
