In golf one frequently looks for ways to convey concepts with images or expressions. “CP/CF release” is a part of this lot. CP/CF release implies a centrifugal or a centripetal force acting on the club through the release phase of the club through the bottom part of the swing. In either...

I have put together a playful exercise involving very basic concepts such as mass, mass distribution and swing radius. Have a look and see if you like to participate. :cool: Some playful tinkering with swing radius and mass distribution

There is some subtle pleasure seeing those two weird characters, nmgolfer and jeffmann, having a real go at each other for a change. They posted having lost respect for each other. How sad. I do sympathize. ;) Normally they work in tandem dishing out generously criticism but often smearing and...

Those having spent some time studying TGM are likely accustomed with the concept of 'Geometry of the Circle'. It might perhaps come as a surprise but, even if a bit contrived, it is possible to have the clubhead nevertheless follow a perfect straight line trajectory for quite some time through...

I would not be surprised if some are a bit frustrated with Miura's parametric acceleration having no clue what it is all about. It is with this in mind that I have put together this article using a more intuitive geometrical approach towards a physical understanding of parametric acceleration.

Golf kingdom is permeated with the idea that centrifugal force plays a cardinal role, specifically in the release of the club through the impact zone. This notion is really omni present in golf instruction, books, articles, posts and even in golf science. I have analyzed the various torques...

Whenever we are dealing with image processing equipment there are two steps involved. - An image is formed through a lense(s) onto some surface, where it is processed/captured. - The captured image is viewed subsequently by reproducing the image on some screen. For instance, Taking a...

In “The Talent Code” by Daniel Coyle there are fascinating ideas about developing skills and the teaching aspects of developing such skills. For instance, Ron Gallimore, professor emeritus at UCLA, about teachers: “A great teacher has the capacity to always take it deeper, to see the learning...

Joe Norwood is perhaps one of only a few golf instructors specifically mentioning the role of the trail shoulder in his book 'Golf-O-Metrics'. ''Stead steady, toss the hand/wrist/forearm to the right shoulder, then use the right shoulder to power the downward thrust. Using the right shoulder...

We have instruction and the result, a golf swing. Instruction is bewildering in its variety but yet the resulting swings remarkable similar. When someone demonstrates hitting and swinging quite likely it will be difficult to notice any difference even with close scrutiny. What feels as totally...

Brian, I don't agree. Centrifugal force is not fictitious. In a golf swing it is as real as you and I existing. I can't blame you for your definition of centrifugal force as it is common to find it mentioned this way in many official science textbooks. It is frequently defined as the inertial...

On occasion one will find instruction or forum discussions mentioning that ground reaction forces should to be used efficiently, or perhaps even suggesting to be a possible source for additional power input to the golf swing. Let's be clear about this... ground reaction forces are indeed just...

Two distinct golf teaching philosophies of 2D flatland golf instructors. :D Have a look for yourself and don't hesitate to post your comments. :p

On the website, +PLUS magazine ...living mathematics , maintained by John Baez, a mathematical physicist at the university of California, I found an interesting phrase, which reminded me of the difficulty for some on agreeing what it meant to swing left past impact. 'Ask two people facing...

Brian brought up the subject of applying a force across the shaft (FATS) in the thread - 'Dark Ages'. This reminded me of this everlasting debate of hitting versus swinging. Surprisingly TGM does not allow for simultaneous swinging and hitting. However it only seems logical to use both trail...
