Next time you hear someone yell "FORE!" on the Golf Course you might take special
heed of that well-known expression. Let me give you some facts, supplied to me by
friends who do important testing for equipment manufacturers in the golf industry, that are
absolutely fascinating:
The momentum of a well hit drive just after impact is roughly equivalent to that of a bullet
fired out of a typical 22 caliber rifle.
The golf ball, which weighs 1.62 ounces, can exceed 150 mph after impact with
a driver swung at 110 mph.
Just after impact, a person hit by a golf ball would experience similar contact forces
as that of being struck by 22 caliber bullet fired from a rifle with a speed of 750 mph.
Remember this the next time you yell "FORE!", or hear someone yelling that in
your direction. Fortunately, golf balls experience drag forces during flight that reduces
its velocity by more than 50% by the time it lands.
