One of the Pro I used said its important to know how a golf club works... then he ask me to read a 900 pages book he wrote.... which a section described how golf club works....
Put it this way, the book still as new as I receive it....
I am not a reader
I suddenly thought about this at work so I did a quick dig up on the internet and I found the following....
In the 450 millionths of a second that the ball and club are in contact, as shown in the animation to above, the ball does several things. First, it deforms quite a bit, flattening against the face of the club. As the ball begins to rebound to its normal globe shape, it starts to slide up the club face. Finally, just before it leaves the club, the ball returns to its familiar shape and begins to roll up the face. By the time the ball has left the club face, it is spinning quite rapidly. According to the USGA, a ball hit by a wood or one of the longer irons (3 to 5) will be spinning at approximately 3,600 RPM when it leaves the club. The same ball struck by a pitching wedge will spin at nearly 6,000 RPM when it leaves the club.
The Sole
Ideally, the sole of the golf club will minimize the twisting of a bad hit. In woods, the broad, flat sole with rounded edges helps the head glide over the surface of the grass without digging in. Shots using irons tend to take patches of the turf away (the patch is called a divot), so the sole of irons are designed to slice through the turf evenly, without twisting or unexpected tugging to disrupt the golfer's shot.
After I read all these I thought... "Ah.. okay... but what it does to help me swing better Sherlock???"
I think I am just pure stupid/idoit/intellengent challenge or alikes.... would any of you guys able to brighten me up how it help me play better golf?
Thanks
