The guy I used to golf with was a mechanical engineer (naturally) and
was a very good at golf. He took the game seriously and tried to
instruct and correct my crude game. I remember him reminding me of
Einstein's equation of energy equals mass time velocity squared.
He was of the opinion that the big, fat driver heads popular at
the time were nonsense. The leverage was in velocity or the speed
of the head as it hits the ball. Made sense to me because back when
I was a kid my father who was a baseball nut and admired Ted Williams
used to tell me the same thing. Williams didn't use a heavy bat.
He just swung a lighter one fast and timed the snap of his wrist
to the exact moment the bat contacted the ball, accelerating the
speed of the bat.
The big driver heads are very light. The extra size is to enable hitting the ball easier. They look
heavy, but they're lighter than they were years ago.
The higher the velocity, the greater the force, and the greater the distance - IF the damn ball is
hit on the sweet spot of the club and the swing is along the target path allowing the club face to
be perpendicular to the target path. The speed part is the easy part!
Another peculiar thing about golf is what I call 'golf ball geometry'. From a hundred yards out a
ball hits the green and is within two yards of the hole. But, when one gets to the green, that two
yards has grown to ten yards (because of the perspective). For some reason, the distance from the
ball to the pin *never* gets shorter as one approaches the green!
Lots of science, math and optical illusions in golf. :-)
