Golf Ball Dimples - How Many?

A Kidzworld member asked the Zone, "How many dimples does a golf ball have?" We put this question to the Sports Lab which now has the answer.

Rather than actually count every single dimple on a golf ball, we asked Bob Thurman, who tests and designs golf balls for Wilson Sports. He says a golf ball usually has anywhere from 330 to 500 dimples - depending on which company designs the ball. The dimples help the ball travel farther and higher.

Dimples first appeared on golf balls more than 100 years ago when golfers discovered that balls which had been scratched or roughed up traveled farther than smooth balls. "Dimples are what gives a golf ball lift. They create two layers of air going around the ball. The top layer is going faster than the bottom layer which creates turbulence. This reduces the drag and allows the ball to travel farther than a smooth ball," says Bob who is a trained engineer.

Different companies have designed golf balls with different numbers of dimples to allow the ball to travel farther. This is quite a science and involves weeks of testing and retesting. Companies can even design golf balls to suit the swing of individual golfers. So a ball used by Tiger Woods might have a completely different dimple pattern than one used by David Duvall. The ideal ball will usually have between 380 and 432 dimples.

If you've got a question about science and sports, to Kidzworld. We'll do our best to give you an answer - or at least a pretty believable story.

Cheer-leading is a sport - most people think that it is not - but it is Yes it looks like they are just cheering on the football players - but their routines and being able to hold up girls over their head takes strength, and they work really hard to make everything look good.

I liked cheering for the underdog, so I've always cheered for the Cavs. I'd like to see how this year's line-up goes, though our past best point guard left for the Celtics.  :/

Mayo lost against Dublin again. 1-16 to 1-17. I support Mayo, and I am horrified to be honest. I don't want to sound like a sore loser, but I think Dublin fouled Mayo way more times than they were punished for it. Mayo rarely got any frees and the last free of the game was a minute before it ended and Dublin were taking it from very far away. Of course, they got it. Up until then, it was 1-16 to 1-16. I guess Mayo won't be taking home the cup again for another year.
