Why are there so many holes in golf balls
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 is there a hole in the golf ball
Generally speaking, the smaller the wake range, the greater the pressure behind the sphere and the smaller the air resistance to the sphere. The small pit can make the air form a thin turbulent boundary layer close to thWhy are there ants on golf balls  and the direction of lift is upwarde surface of the ball, making the smooth air flow move more backward along the ball, thus reducing the range of wake. So don't underestimate the hole in the golf ballWhy are there holes in golf balls
First of all, the concave convex surface of the end stream golf ball is the result of natural selection. The surface of the first golf ball was smooth. 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 generatorsThe surface of table tennis and bowling is smooth. Why is the surface of golf full of small pits

The feeling is to increase friction and facilitate hittingPlease smell: Why are there pits on golf balls
Aerodynamicists (scientists who study the flow of air) divide the force exerted by air on moving objects 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 and perpendicular to the direction of motion. A high-speed golf ball has a high-pressure zone in front of itWhy 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 airWhat kind of insect is red fire ant
Worker ants have two ventral stem nodes; Tentacles are generally 10 segments, and the last 2 segments are hammer rod-shaped; The longitudinal eminence extends forward into the teeth on both sides of the labial base. Male and female ants each have one eye. The antennae of female ants are generally 11 segments and that of male ants are generally 12 segments. There are no thorns or teeth in the chest and abdomen.

Why is the surface of a golf ball full of pits? How much force can the ball bear at the moment of hitting? If there is a pit, the friction between the pit and the rod surface is relatively large. It can fly higher and farther, and it can also rotate. It is also easier to stop the ball with pits on the fairway green. It is similar to the sole of running shoes and football shoes
