A book named "The science of Golf" published in Feb, 2009 not only mentioned CF but also with calculation...Dr John Wesson....who are you?

Yes that guy.... Just because a book gets published does not mean the author knows what he/shes talking about. At least in his physics of soccer book... Wesson doesn't know what he's talking about (with respect to the physics of release). In figure 2.3 of that book he's got one of those (wrong) imaginary arrows I refer above.
There is no force out there... CF or otherwise! The only force the lower leg (in this case) or golf club (in our case) experiences is the force applied at the at the knee or at the hands (disregarding the minor contribution due to gravity)!
Try thinking about it this way.... Forces are vector quantities, they have both direction and magnitude. If you draw an infinite line in the direction of the force and if that line does not happen to go through the center of gravity of that object then when that force is applied it will cause the object to not only translate but also rotate. Grab the periphery of almost any object and pull... does it rotate? Its inertia that causes the object to not only translate but also rotate when the "line of action" of the force does not go through the CG. In essence... THIS not CF is what causes release.
PS LynnB we will see... on second thought no way... pissing matches are for school yards
Actually, having been exposed in your opening post as "ignorant" and a "posuer" -- BTW, the correct spelling is poseur -- with regard to scientific principles, I proposed a golf match, not a "pissing" match. And not in a "school yard", but on a championship layout. Guess you weren't feeling lucky.
The truth is, no_mind, that despite your condescending and incorrect labeling, we here at LBG have learned to make the golf ball behave. And, despite your counsel to our readers that they "humor" us and "move on", we have demonstrated our ability to help our students do the same.
Where Vfict (r) is the potential responsible for the centrifugal force: fc = −ω×(ω×r) = (ω2−ω ωT)r
.
Vfict (r) = −1
2 rT(ω2 − ω ωT)r
Now, Rs and RJ are parallel and MsRs+MJRJ =
0.
[Note that if a particle is moving then addi-
tional Coriolis forces act that are not mentioned
in @
@rVeff (r), so we can’t determine stability from

Any questions?
Yes Rob, are you sure that your calculation 2 rT(ω2 − ω ωT)r should not be 1.8 rT(ω2 − ω ωT)r ? Just wondering.
That depends on the wind direction, but wait, I can't see the wind. Wind must be fictitious. The tide is in the coffee cup. That one still makes me scratch my head every morning........but I know its true.

Right you are, BBax . . . There is a tide in your coffee cup! Difficult to see, I'll admit. So, for the best observation points:
Low Tide -- Starbucks.
High Tide -- Dunkin' Donuts.
Somewhere in between -- Waffle House.
Each is best observed at its extreme during the Full Moon, ideally at the Bay of Funday in Nova Scotia, Canada. But, if you're on the equator . . . furgeddaboudit. Tides ain't hap'nin, either in the oceans or in coffee cups. http://home.hiwaay.net/~krcool/Astro/moon/moontides/

Often wondered what was going on with that Jack in the Box coffee.
