Let me guess, Johnny Miller was the announcer.

Damon gives an excellent explanation from another thread:

Depends on your definition of heavy hit. As defined in the above thread, then yes, that version of heavy hit is a fairy tale. However, if you understand springs and masses attached to springs, then one can arrive at a different interpretation of "The Heavy Hit" that does have some validity in the golf swing.

f=ma Force = mass x acceleration. It may be controversial but I have seen the so called "heavy hit" effect in multiple sports. People into velocity will argue against but expirentially I have found some folks have a "heavier" hit than others. Could be differing reasons behind it but I know from experience if you hit something and you have weight behind it the implement you are striking it with experiences less deceleration and imparts more force to the object being struck. If a 4,000 lb truck runs into a 1,000 lb go cart at a given speed its one thing if a 50,000 lb train runs into at the same speed the effect differs. f=ma

There is no heavy hit in the golf swing period. It may sound different but that doesn't make it so; it has been proven multiple times mathematically that it isn't possible. Do a search on the board for your answers.
There is ZERO you can do to overcome deceleration of impact collision or add any extra mass to the clubhead in the downswing.

I guess you're just one of those folks that's going to agree to disagree despite mountains of evidence to the contrary. This subject is already a closed case. And using the equation f=ma doesn't make any sense, because the m in the equation would be the mass of the clubhead. As Jim said it is impossible to add mass to the moving clubhead. Clearly you already have your mind made up though, so if you want to go on believing junk science then go right ahead.
If you want some real equations, check out Mandrin's "Physics of Impact" in this thread. I'm warning you though, it'll make you dizzy.

Is the club head flying around by itself? Or is it connected to the shaft which is connected to the hands which are connected to the arms which are connected to the body?
The force being applied to the clubhead via the shaft is important to consider in this analysis not simply thinking of the clubhead on its own as if I threw a disconnected clubhead into the ball or maybe shot it out of some kind of gun.

f=ma is not the correct formula to use in the analysis of impact physics.Go to the bottom of the science class for you.E-
This has been covered to death already.Do a search.Nobody wants to waste time with the f=ma argument anymore.

The clubhead acts like a rock on a string during the swing and the impact interval thus even if you could PHYSICALLY (which you can't) try to add mass it wouldn't increase the mass of the actual clubhead.

I'm pretty sure that this is actually what is going on. The clubhead acts like it is disconnected from the shaft. I don't know the particulars but I know this concept is one of many that I've learned here that just freaking blew my mind. You would do well to find info here from the Manzella crew, believe it, and use it because you will be a better golfer.

HMMM, I am no scientist but after a quick search I notice most people's current belief is that its all about velocity. Maybe what I have seen and experienced is related to what trackman calls smash factor not a HEAVY hit simply a very SQUARE hit.
A very pure hit has such a nice sound and feel expirentially I have a hard time believing it's not a Heavy hit. It seems intuitive to think that a well supported clubhead would have less deceleration during impact and therefore impart more energy to the ball. Doesn't the force through the shaft resist deceleration? I have a hard time believing a clubhead swung 100 mph supported by a string applies the same force as one attached to a shaft. Maybe this is why I strike it better when I don't hold onto the shot the fully released shot applies slightly more velocity to the clubhead which is the key factor of the impact. Anyone have input or links on this?

Grahler you are new here and i am going to treat you as someone who has general interest in this subject, however please understand we get a lot of people coming here just trying to stir the pot when it comes to being able to resist deceleration and create a "heavy hit". Let me address the above: No it isn't all about velocity, it is more complicated than that. I too am not a scientist however the Manzella Academy deals directly with actual scientists and their findings are correct. You cannot resist deceleration of impact and you cannot add speed through impact it is physcially not possible.
Can you, through technique, improve smash factor in the golf swing? Yes! However that isn't resisting deceleration through impact, that is simply delivering the golf club in a proper fashion to the ball and achieving the maximum smash factor possible. However once, through technique, you achieve maximum smash factor there is nothing else you can do.
Grahler, again you mention you are not a scientist and it's ok to go off your intuition and ask questions. However people much smarter than most of us have figured this out and if you don't want to believe it that is ok too; however just note that just because you don't believe it doesn't make the actual scientists and physicists who do have the right answer wrong.
Please do some searching on the board and read through the threads, there have been many which is why i don't want this to become another one. As johnnymarlboro posted above here is a great thread to get you started:

The problem with the term "heavy hit" is that it is a non-scientific term that is open to be interpreted many different ways. How the term is being used in mainstream golf talk to describe impact is probably not the best use. I 100% agree with the posted links and opinions of Jim and others that there is no "heavy hit" at the moment of impact.
If the correct terms are used, I suppose people would be more open to discuss other uses of the term "heavy hit".

What have you seen? What supports your concept of a heavy hit besides " the sound and feel". What exactly is a heavy hit in scientific terms can you explain it or do you just go on your intuition? How can one achieve this Heavy Hit?
