I've heard Yoda talk about "effective mass" being more important than clubhead speed. But I must confess, it's not a concept I claim to understand.

That dog doesn't hunt.

1. Your mass compared to the 2x4 is not the same as the clubhead to the ball.

2. Your mass compared to the car is probably closer the clubhead/golf ball relationship, maybe a bit higher.

3. Both the 2x4 and Car would equate to being the clubhead. In effect we have two different clubs in this example.

I guess I am missing your points. The golf club, the handle/grip is being moved, it doesn't matter what is moving it if in fact it can move the same as another. It generated velocity, acceleration, it has equat mass (clubhead) so with all this being equal, both will act the same when striking the golf ball.

It is only when the resistance exceeds the applied force generation of one and not the other, will it act differently.

If we accept the fact that every component lags the previous component, the feed back time to effect anything other than the hands is beyond the impact/separation time which once the ball is gone, loss of acceleration at that point will not effect the shot.

We are talking about the effect of hitting the golf ball, not how one might precieve the follow through or lack of?

I am beginning to think I have misunderstood this exercise. Equal power applied is equal power applied. Meeting resistance is equal for both.

Oh...my dog most definitely hunts!

Now about my post. The point I was making is simply twofold:

1. If two items with different mass strike an object at the same speed, the item with more mass does the most damage.

2. This was more of a question on my part - how do you create more "effective mass" with a golf club so that you get to do more damage?

Now....this leads me to poke on point #2 a little more:

How does "lag pressure" create more effective mass? And is "lag pressure" different from "clubhead lag"?

"Clubhead lag" to me is simply maitaining the lag as long as possible in the golf swing. If my hands are approaching the ball and the clubhead is still above my waist, I've got a tremendous amount of "clubhead lag" which means the clubhead must travel MUCH faster to square up with the ball at impact. As opposed to a situation where my hands are approaching the ball and the clubhead is below my waist - in this case, the clubhead does not need to travel AS FAST to square up with the ball as my first example.

So I've created more clubhead speed by maintaining more cluhead lag.

This obviously didn't create any more mass in my clubhead. Perhaps the answer is - lag pressure is simply the feeling of creating more cluhead lag. And it's really the resulting increase in clubhead speed that hits the ball further. (And you can do this without swinging harder or faster.)

Perhaps this is just a semantics issue, but nothing I described above really creates more "effective mass". I've just described how to effectively create more clubhead speed by maintaining more clubhead lag.
