What is the function of the surface dent of golf balls but the surface dent type is used

What is the function of a small hole on the surface of a golf ball
Although today's standard golf balls have different brands, they all use the surface dent type. If it is a golf ball with smooth surface, after being hit by a professional player, the flight distance is far less than the ball with grooves on the surface. Some people have tried that a smooth ball can only fly 65 meters, while a dented ball can hit 275 meters. SoWhy do golf balls have many pits
A golf ball with smooth surface can only hit tens of meters in one shot, while a "pockmarked face" golf ball full of about 500 round or hexagonal pits can hit more than 200 meters. What's going on? Why does a golf ball go further when its surface is full of small holes? Some people say that the air resistance will be smallWhy is golf uneven
The uneven surface of golf balls is actually to make golf balls fly farther and have less resistance. In fact, when golf was first designed, it was not uneven, but in the process of slow development, people found that it seemed that the uneven shape was more conducive to the flight of the ballWhy is golf uneven
It is easy to explain this phenomenon by sticking your hand out of a moving car. Aerodynamicists divide this force into two parts: lift and drag. The action direction of drag is opposite to the direction of motion, while the action direction of lift is upward. Small pits on the surface of golf balls can reduce air resistance and increase the lift of the ball. OneWhy are there so many holes in golf balls

Increase the distance the golf ball travels. The friction of turbulent flow is larger than that of laminar flow, but compared with the form resistance, it plays a small role, and the total resistance is smaller. Small protrusions on the surface of golf balls can also promote separation, but the interference of protrusions on the flow is difficult to control, resulting in some lateral forces (also known as lift)Why is there a hole in the golf ball
So don't underestimate the hole in the golf ball. It plays a great role. When the ball club contacts the ball, it can increase the friction, increase the reverse rotation speed, and make the force on the ball uniform as the groove on the rod surface; In flight, under the influence of aerodynamics, it keeps the sphere rotating properlyWhy should the spherical surface of a golf ball be full of pits
When a "pockmarked face" golf ball flies, some small vortices will be generated near the pit. Because the fluid molecules near the golf ball surface are attracted by the vortices, the separation point of the boundary layer will be pushed back a lot. Therefore, the vortex area formed behind a golf ball is much smaller than that formed by a smooth ballWhy is the golf surface pockmarked
Shallow dents on the surface of golf balls are natural selection. Initially, the surface of the golf ball was smooth. However, golfers have noticed that as the golf ball gets older, it will be full of scratches, potholes and cuts, which seems to make the ball fly farther
