Explain why the surface of golf balls is rough and small with physical knowledge
Put your hand out of the driving car and find that the ball with a hole flies farther than the ball with a smooth surface According to the data, for exampThe rougher the golf surface, the better  according to the datale, this imbalance can generate upward thrustExplain why golf balls have rough surfaces with physical knowledge
It is easy to explain this phenomenon by sticking your hand out of the moving car. AerodynamicThe rougher the golf surface, the better  according to the dataists 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 should golf balls be made with uneven surfaces instead of smooth ones
At this time, the large whirlpool area formed behind the golf ball is much smaller than the smooth golf ball, so the resistance of the golf ball in the process of flying will be greatly reduced. In addition to this effect, the concave surface of the golf ball will also provide some lifting force for the golf ballWhy is the surface of a golf ball pockmarked
The reason why the golf surface is designed with many small pits is to make the golf fly further. Statistics show that the flying distance of a golf ball with smooth surface after being hit by a professional player is about half of that of a golf ball with pits on the surface. From the structure of golf to divideGolf balls have low resistance due to rough surface, so why does the plane require a smooth surface
This is aerodynamics, you shouldn't ask here! To put it simply, aircraft and golf are both different in terms of sports environment and volume! The potholes on the surface of the high ball are mainly to make the air pass through the ball without causing a spiral cavity behind the ball, which will affect the flight of the ballWhy is golf rough rather than smooth? What is the reason of fluid mechanics_ Hundred
The surface of the ball is not smooth but dented. The reason is that in aerodynamics, the ball is placed in the air flow and surrounded by a thin interface layer. If the surface is smootThe rougher the golf surface, the better  according to the datah, the interface layer is easy to peel off, resulting in air flow vortices in the rear, causing higher pressure in the front, while the air flow behind the dented ball does not drop much, so that the ball flies fartherGolf balls have little resistance due to rough surface, so why
As far as I know, there are more than 300 holes in the golf ball, and the average depth of each hole is about 0.025 cm. In fact, many hollows are deliberately made on the surface of golf balls, 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 ballIt can be observed that the surface of golf balls is uneven. Do you know why_ Baidu
Golf has now come into the view of ordinary people. It has been called "noble sport" before. With more and more people participating, you will also notice that the surface of golf is not smooth and there are many uneven pits. What is the reason for this? Next, we will make a specific analysisWhy is the golf ball rough (PIT) why not use a smooth surface
The surface is smooth and the moving direction is fixed, which determines the force of air turbulence on the ball, that is, why the trajectory of table tennis has a horizontal arc. There are pits on the surface, which makes it difficult to form a certain air turbulence. What can be formed is only a lot of turbulence with different directions and little force. They interfere with each other and cancel each otherWhy should The rougher the golf surface, the better  according to the datagolf balls be made with uneven surfaces instead of smooth ones
When we put the golf ball in the air, the golf ball will exert a force, and then the golf ball flying in the air will be surrounded by a layer of airflow. At this time, it is easier to peel off from the air than a smooth ball
The rougher the golf surface, the better according to the data
