AAAAAAGGGGHHH!

And that cat-o-nine tails... its to keep the kinetic chain gang in-line right?

Sigh...

I see these funny little diagrams with an arrow labeled CF appearing to cause "release"... Uh.... No... thats not the way... awe nevermind .... resistance is futile

P.S. seems we lost Jeff... life goes on I suppose

That "funny little" CF force arrow is not random. It is precisely parallel to the left arm (2-K #1 and #3) or in line with it (2-K #2).

Out of curiosity, what is your explanation of the dynamic?

BTW, give it your best shot, because this is going to be an extremely short-lived interaction.

You mean dynamics of the release? What causes it if not non-existent "CF"?

That explanation be here: http://nmgolfscience.tripod.com/release.htm

*Warning*

Requires a high school physics level of understanding... peruse at your leisure or don't... It does not matter to me and I won't be offended if you opt out. I'll be back in about a week .... business calls.

Regards...

Oh, now I get it. Thank God I bumbled through high school and Georgia Tech. That settled, and when you get back next week from "business" . . .

Let's play golf.

I'll take the equally deluded Ted Fort, Jeff Hull and 12 Piece Bucket -- -- against the best ball of you and any three of your referenced Cambridge physicists.

Eighteen holes at Atlanta CC: You guys take carts and play the gals' tees (any gal physicists must play from there, too ).

We'll play the tips and carry our own bags.

The Rules are the Rules: Play by them -- including the ball 'as it lies', no 'gimmes' and count every stroke.

Loser pays all expenses, including green fees, meals, lodging and transportation.

Should be fun.



P.S. For the rest of us: The sound you hear now is no mind scrambling for one or more "referenced physicists" with a scratch handicap, a penchant for the Ladies Tees and looking for a U.S. 'getaway'.

Sounds like a lot of fun
I would like to be there with a videocamera.

And there's a story right there for Mark Frost to write.

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.

Have at it I've got to catch a flight now...

PS LynnB we will see... on second thought no way... pissing matches are for school yards

Yoda - You really need to pick three completely deluded CF (or whatever its called) swingers. Ted is disqualified, Jeff admits he probably pushes through impact, and Bucket uses 72 different patterns during a single round.

I suggest EdZ, MikeO, and Collin Neeman.
