Transfer of Momentum occurs in both cases.

What is really being considered is that at impact, the resistance the clubhead encounters will reduce the acceleration. In the first case, no golfer - just a club, it is assuming that this resistance will be meet with effort to overcome, whereas with the golfer and mass of golfer somehow it will either be overcome or reduced.

In this example we have assumed that a golf club with a golfer can achieve the same acceleration as one with a golfer. That being the case we must then say the self powered golf club can and will in fact work as the one with the golfer and mass.

Newton's 3rd law - "In a system where no external forces are present, every action force is always opposed by an equal and opposite reaction force." or "When one body interacts with a second body, the force of the firs body on the second is equal is magnitude but opposite in direction to the force of the second body on the first. F2 on 1 = -F1 on 2" appllies.

As I stated the clubhead and ball no not of the golfer (golfer could be 1 foot tall, 300 lbs or 8 foot tall and 100 lbs), but what properties of the clubhead exist and the golf ball.

This could, maybe not the best example, equated to when you enter a curve and then accelerate out of the curve to hold the curve path. Don't want to discuss centripetal or centrifugal forces here. What I am reading and hearing, is that the golf club with the golfer will in fact apply additional force (be it active or inactive) to attempt to overcome any resistance of impact. I submit that the self powered golf club will do the same since it was capable of achieving the same acceleration, etc. that the golfer powered golf club.

This is all theorical (don't know of a self power golf club except that one that used a gun shell to move pin into the ball), for golfers of different masses and same techniques we find that we have the same situation and that is both using the same technique, should be able to compensate equally.

Another side note, since the golf stroke (proper technique) will not achieve it's maximum's till 'inline' relationships are meant, both golfers of varying sizes still should have sufficent force to be applied before reaching thier maximum.

Hope that was clear.

Very interesting Mr. Martee!!

It sounds like what you believe, as it would apply to human golfers... is that the big guys (Big Cat type guys) that hit the ball further than the little guys with similar type swings... are doing so primarily because they can accelerate the club faster, and that their MASS or size has nothing to do with it. The tall guy's longer levers, of course, is a different thing(leverage and arc). Does everyone agree... EdZ... what do you think on this?

Your mentioning of centrifugal, centripetal, and curvilinear are also good ideas for DISCUSSION in the LAB!!

What about the LONG CLUBS?
