Now why dont you argue the science instead or is it just a Boys Club and when you get out of your depth just as was the case with Dr Jeff Mann ( although he was a pain in the butt).
Pistol, I am sure you will agree that having many friends and developing many wonderful relationships with people on this forum can be quite distracting. Would you not agree?

Physics changes depending on the frame of reference or does it.

The following two posts that I combined into one took place in 2006 from one of my favorite posters, “ThinkingPlus” aka Steph (a Physics major, who I wish would post more often). Should she make an appearance, I hope you don't mind if she says hello:

"Centrifugal force is a convenient term describing an effective force present on objects in a rotating reference frame (an object undergoing centripetal acceleration). It is what our bodies, arms, and hands "feel" as the pulling away from the center of rotation during a swing. This concept and feel can be used as an aid to creating angular velocity. That is all that is claimed within TGM to my knowledge. Angular velocity and acceleration is what ultimately matters."


The laws of physics in a non-inertial frame:

"The frame of reference is always a choice. The laws of physics in this case are invariant regardless of frame of reference. However, the explanation of what is going on varies. A rotating reference frame is proper during the downswing since that is the frame of reference the golfer lives in so to speak. You wish to keep things in a non-rotating reference frame because it makes the centrifugal force explanation less applicable.
This whole argument is splitting hairs about reference frames and centrifugal force. It is pointless to the golfer. One will get the right answer whether one invokes the concept of centrifugal force or explains the phenomena as inertial resistance of the clubhead mass. Basically it all comes down to what folks will understand more easily. Centrifugal force explanations are more intuitive to understand for the majority than inertia, which is why it is more generally taught that way in universities across the world (to physicists). It is nice that you learned your physics a different way, but the answers all turn out the same. I suspect we will just have to agree to disagree."
