Why is the surface of a golf ball uneven
The original golf balls were actually made of feathers, and the outside oWhy is there a scratch on the golf ball  the outside of this kind of ball is sewn with cow leatherf the balls were sewn with cow leather. However, it was later found that the ball seemed to have insufficient strength when hitting, so the rubber ball appeared in the later stage. Although the rubber ball is more powerful than badminton, it is too powerful when hitting the ballWhy are there holes in golf balls
There are more than 300 holes in the golf ball, and the average depth of each hole is about 0.025 cm. In fact, the golf ball surface intentionally creates many concave holes, which is the result of dynamic aerodynamics research. The existence of these holes is precisely to reduce the air resistance and increase the lift of the ball, so that the golf ball can fly fartherWhy do golf balls have many pits
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, but generally the rougher the object surface, the greater the friction resistance, and the contact surface between air and golf ball is full of small pitsWhy are there many pits on the surface of golf balls
The surface of the golf ball was deliberately dented. The shape of golf balls is one of the achievements of aerodynamics. This is related to the Why is there a scratch on the golf ball  the outside of this kind of ball is sewn with cow leatherturbulent transition and separated flow phenomena of the flow around the sphere. When the flow around a smooth sphere, the turbulent transition occurs late, and the regular flow corresponding to the turbulence is called laminar flow. AndWhy are there holes in golf balls

The other half comes from small pits, which provide the best lift. Most golf balls have 300 ~ 500 small pits, and the average depth of each pit is about 0.025 cm. Drag and lift are sensitive to the depth of the pit: even if there is only a small difference of 0.0025 cmWhy should the spherical surface of a golf ball be full of pits
In order to fly, airplanes usually need as smooth a surface as possible and a streamlined fuselage, while golf balls are just the opposite. There are about 300 small pits on the surface of golf balls. Why is golf designed like this? Among the various ball games popular in the world today, golf can be called "the elderly"Why are there many pits on the surface of golf balls
So, why did the cave fly far away? The smooth surface originally thought that the air resistance was small, and it seemed that it would fly farther. How could it be the opposite? When the golf ball is placed in the air stream, it must be surrounded by a thin interface layer At this time, the air interface layer of the smooth ball is easy to peel off, and an air vortex is generated behind the ballTable tennis, bowling and other surfaces are smooth. Why is the surface of golf full of small pits
When there is no air blowing, the equal arm lever keeps balanced, indicating that the gravity of a and B balls is equal. When the wind blows at the same speed, the force analysis is made for the two balls a and B. both balls are subject to two forces in the vertical direction, that is, the downward gravity and the upward wind force (the magnitude is equal to the resistance of the ball)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 air
