为了飞行,飞机通常需要尽可能的光滑和呈流线型,而高尔夫球却恰好相反。高尔夫球上的大约300多个小坑使它能够以比光滑的球高三倍的速度飞行。是这么回事……使飞行的球减速的空气阻力一部分由摩擦造成,另一部分是由被称为湍流的东西导致的。空气湍流充满了漩涡,而漩涡则从球那儿偷走了动能,使球的速度 To fly, the airplane usually needs to be as smooth and streamlined as possible, while the golf ball is the opposite. About 300 pit holes on the golf ball make it fly three times faster than a smooth ball. That’s the case ... part of the air resistance to decelerating a flying ball is caused by friction, and the other is caused by something called turbulence. The turbulence of the air is full of whirlpool, while the whirlpool steals kinetic energy from the ball, making the ball speed
