F=MA

MOMENTUM: mass in motion ( according to the referenced Glenbrook link)

Still... would not a 100lb. golfing machine hit the ball further than a 1lb. golfing machine, with all other factors being equal?

if you're asking whether a 100 lb clubhead would hit the ball further than a 1 lb clubhead if they have the same acceleration at impact then i would say yes...if you mean that a 100 lb machine and a 1lb machine both swing the same clubhead, in the same way, to the same acceleration at impact, then i would say no...
