Just proving the fact that, swing speed being equal, more mass equal more distance. However, nob makes a very obvious and valid point, the human element adds many variables.

I understand the direction golf is going...but I also understand it's because (in theory) a lighter club is supposed to allow the player to swing faster. Just know that whether it's F=ma or the Sevendreamers equation, physics proves that a heavier club head equals more distance.

I just saw your edit...I'm not at an airport but I'm bored and can't sleep.In your example, you're correct in that there is no acceleration...BEFORE contact. Knowing Newton's 3rd law we know there's an equal but opposite force applied to the truck and your body when they do contact. We can either multiply the mass of the truck by it's minimal negative acceleration as it smashes you into it's radiator or we can multiply your mass by your nearly instant acceleration from 0-60mph. Either way, it's going to be a lot of force due to significant mass or significant acceleration, respectively. Newton's 2nd law is definitely F=ma, not sure why the site you found shows something different.

I'm still calling out the assertion that a lighter weight equals higher ball speed (unless it increases head speed) but other than that I want to go to Japan more than ever now.

I had the AF-Tours and I can't say I felt the offset was that much reduced...

Lol, he's wrong...but good luck convincing him of that!

No kidding!?? Did he not know the conforming rule doesn't affect amateurs until 2024?

For whatever reason the Personals are just plain short...shafts and lofts don't seem to matter.

I'm still amazed why people care about conforming grooves when that rule doesn't apply to ANYONE outside the PGA or playing in an Open qualifier.

Note to self...write apology letter to physics professor and admit I did one day finally use physics outside of school. :)

Acceleration doesn't equal velocity squared. It's the change in velocity over time. Or, if we're talking about head spead velocity squared divided by the radius of our swing arc.

Good Lord those are beautiful! Is that a hint if onset I see or just the camera angles?

I also dropped down a half flex (from s to r+) in the C-Tapers and am very happy with the results.

None of us actually swing at our max and I've found that I have what I call my "comfort speed". It's the ss I maintain comfortably (and it fluctuates day to day). However, that speed tends to stay the same for me if it's a light head or super heavy one...my body just tends to find it's comfort zone. Because of that I can swing an overly heavy driver, not lose any head speed, and gain distance. Obviously if I was swinging at 100% effort all the time, then yes, I'd swing a lighter driver faster than a heavy one. But that's not the case for me, nor for most people I'd be willing to bet. I believe you're right about the concentration of mass at impact. The more mass directly behind the impact point, whether it's a compact head or a heavy head/light shaft combo, will increase force, therefor distance (all other variables remaining constant and assuming you always hit the sweet spot).

"Unique feel" is mpbachman's polite way to say if you don't hit them flush they feel like CRAP! ;)

The original C-Tapers. The C-Taper Lite actually specs as a lighter KBS Tour with a C-Taper finish so stay away from those if you're trying to reduce spin.

This is one of the reasons I went to C-Tapers...

F=MA is simply Force = Mass x Acceleration. Acceleration is actually more accurate than velocity to describe head speed and ball speed but that's getting nitpicky.Yes, theoretically one should be able to swing a lighter club faster but that's not always the case and it's something I ruled out by saying to swing the heaviest head weight you can that doesn't cause more than a mph loss of ss. But regarding the head weight vs ball speed equation, the opposite ISN'T true...no matter which equation is used. Plug in numbers to the equation from Sevendreamers and you'll find that their equation also concludes the same thing...as long as head speed doesn't change, a heavier head weigh yields a higher initial ball speed. So whoever told you that a lighter club equals higher ball speed was either incorrect or failed to mention they manipulated head speed in their calculations. :)

I never knew that. I do think he was the master of MB iron design. There's not a blade iron today that isn't influenced by his designs.

Depends on the wedges but typically D6-D8.

Have you tried the C-Taper Lites? Their profile is a lot closer to the KBS Tours than it is to the original C-Tapers.

I got tired if the look on my builder's face when I tell him what I want to experiment with...

Btw, pull them apart into webbing before you stuff them in so if you don't put too many in they don't bounce around and it fills up more uniformly.

Not that I haven't tried stiffer shafts but I've always preferred a flex too weak for my ss so this only helped matters. People commenting that my shaft is going to break from my transition gets old though. ;)

You'd be surprised how quickly cotton balls add up... ;)
