What is the use of a hole in a golf ball a hole in the surface will disturb the nearby space

Why is the surface of a golf ball full of pits? What are the benefits of this design
Many pits are made on the golf ball. When the golf ball moves at a high speed in the air, the pits on the surface will disturb the nearby air, and eddy currents will be formed in the front half of the ball, which reduces the pressure difference between the front and back, and also reduces the pressure difference resistance. Compared with a smooth ball, a concave ball moves in the airWhy is there "e; Pit "e
In fact, these small pits are deliberately made, not for good-looking, but for practical reasons. The reason why golf can fly far is the credit of these pits. Although they are not very impressive, golf cannot go forward at high speed without them to reduce the wind resistanceWhy 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 are there holes in golf balls
The concave convex surface of golf balls is the result of natural selection. The surface of golf balls was smooth in the early days. Golfers found that the old ball with traces flew farther after playing for a long time. Aerodynamics experts later discovered that the scars on the golf balls acted as turbulence generatorsCan you ask me why there are holes in golf balls
The small hole on the golf ball increases the friction between the ball and the air, making the air adhere to the surface of the ball more. After passing the ball, there is a downward tilt. According to Newton's third law, since the ball pushes the air down, the air must exert a lifting force on the ball. This lift improves the performance of the golf ballWhy are there pits on golf balls? There are many holes in the surface of golf balls. What's the use
In fact, the ball was originally smooth without holes. By chance, it was found that the ball with holes flew farther than the ball with smooth surface According to the data, for example, people who can play 200 meters of golf in the current situation can only play 40 meters of smooth balls in the same wayWhy is there a hole in the golf ball
Very accurate. It has a lot to do with the structure of the ball. There are small pits outside the golf ball, that is, some shallow pits. They are arranged regularly to prevent the sliding between the club and the ball. As long as the golf ball is hit well, the ball can fly far. Moreover, these shallow pits can reduce the wind resistance and make the ball fly fartherWhy do golf balls have pits
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. A high-speed golf ball has a high-pressure zone in front of itWhy 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 small
