Your dive did not take place live in-front of a world wide audience, and certainly wasn't expected. (If a tree falls in the forest, does anyone hear it?) Didn't think so...

    • Day 296 - 2025-07-23 Got a good hour+ of work in after a few lessons on my off day today. 😉 Recorded some, had mirrors in both places FO/DL. Same stuff, but made sure the right knee was fine.
    • Skill work/clubface control. And…
    • That's not always true. I can apply a force perpendicular to the club… through the center of mass. No rotation. 😉 You don't "apply" a torque. A torque is a result of the force away from the COM. And, per the above, it's not exclusive of the translational motion. Nit-picky, yes. But if we're gonna talk about physics, let's actually talk about physics, and not the ninth grade version of it. I know what you mean, but again, getting terminology right is a big part of this. It's not "behind" the hands exactly as it's already kicked out a little (mostly at that point because  the hands have already slowed a little). They don't really pull up much. They just continue around their arc. The upward pulling here is small. You've seen resultant forces, but may be confusing "holding onto the grip" with how much the hands actually pull upward. To say it another way, you may be confusing the force and the counter force that stops the club from slipping out of your hands. No, because that would be a silly way to look at it given that the golfer is not only holding onto the club  but continuing to push the handle forward, too. Poorly, yes. See above.
    • I just hate when I make half swings I can’t f***** control face or path. F****** half swing back, arms down feeling and block it 30 f****** yards right with a fade.  I can’t even join my game out here at least I have nice views
    • Okay - I'm going to try this again from the top. While that may not be what I said, it is what I meant, although it appears I didn't express it very clearly. The hands apply forces and torques to the club throughout the swing. Any force applied to something like a club can be broken down into the portion of the force that is perpendicular to the shaft and the portion that is parallel to the shaft. The part that is perpendicular to it is applying a torque to the club, which will cause its rotation to change. In a similar fashion, we can look at the club as the sum of two different sets of motion. One of those is how the COM of the club is moving through space. That is affected by all the forces applied to the club, be they from the hands or gravity or the ground or the ball or the air - I think that's about it. The hands in a full swing are going to be the vast majority of those forces. Then the change in location of the COM (translational motion I think it's called) is caused by the net of all the forces applying to it. The perpendicular portion of the force is the only one that matters for rotational motion. That can be considered exclusive of the translational motion. Rotational motion will change with torques applied and can be contemplated on its own. From P6 to P7, you start with the club lagging behind the hands. The hands then pull up (among other things), which is a force applied to the club, not directly through the COM of the club. That means that a torque is being applied to the club by the hands. One which will cause the club to rotate around its COM if we are exclusively looking at the rotational motion. And so, in that sense, the club is rotating around it's COM. That's the part of the motion that I was trying to describe originally. That upward force from the hands is also going to be accelerating the COM around the swing arc due to the net effect of the forces applied to it.  Then, the combined effect of the forces and torques may be to cause the club to rotate around something else in a different reference frame. You can draw a line up the shaft of the club in each frame of video around impact and the point where those lines meet is roughly the center of rotation of the club in the static frame. That center of rotation is also moving through time as you'll see the point where the lines meet is rarely going to remain in the same spot. In any case, this is a different rotation from what I was trying to talk about previously.
