the standard of golf there are 336 pit

golf there are many pits on the surface, what effect?

In fact, the original ball is smooth there is no cavity, and in casual, we found there are actually specific surface smooth ball pit ball fly farther. in accordance with data showing, for example: the status quo can play golf 200 meters well as those who take the same way to fight the smooth surface of the ball, only up to 40 meters. has brought about pit-shaped Another reason is may be due to rotation of the lift (lift).

So, why have the cavity of the fly far? and smooth the surface of the original thought that air resistance is small, it seems distant fly, how would the opposite it? will be placed in the air flow in golf, be sure to layer surrounded by a thin interface layer. At this point, smooth ball, the air interface layer easier to peel, while in the air vortex created behind the ball, so that the rear pressure has eased, pressure on the ball than the front, so the ball is dropped due to pressure difference caused. In contrast, there is a ball pit, because interface layer is not easy peeling, the ball is behind the decline in the power of small, making the ball fly farther.
