How do they put the dimples on a golf ball?
Golf manufacturers don’t put dimples on golf balls because it looks good. There is real science behind their use. A flat or irregular object moves through the air in an inconsistent, fluctuating manner because of how air flows over it. So golf balls without dimples would travel unpredictably through the air.

- Skin Friction. …
- More lift + less drag = more distance. …
Why are there 336 dimples on a golf ball?
Essentially, golfers would have little hope controlling a smooth golf ball. When dimples are added to a golf ball, it creates a tiny layer of air around the golf ball that significantly cuts down drag. This forces the air to flow over a larger portion of the ball, which results in a much smoother ball flight.
What does more dimples on a golf ball mean?
Dimples directly affect ball flight. The higher the number of dimples on a golf ball, the greater the drag over its surface. And this means a lower trajectory.
Why do golf balls have dimples and on average how many dimples are there?
By adding dimples to the ball, golf ball manufacturers minimize drag forces that pull back on the ball or slow it down. Dimples also help lift the ball by forcing airflow downward, which pushes the ball upward. These are the same principles of aerodynamics that airplanes use to fly.
How many dimples does a Pro V1 have?

On American golf balls, there are usually 336 dimples, while there are 330 on a British ball. However these numbers can vary widely. Golf balls have anywhere from 300-500 dimples. Golf ball manufacturers will manipulate the number, shape, size, and even edge angles to optimize ball flight and trajectory.
What are the effects of dimples?
First, dimples allow air to flow more smoothly around a ball's surface, which decreases the wake and low-pressure area behind the ball, resulting in less drag. Second, the dimples increase lift by causing the air to move faster at the top of the ball, creating lower pressure there.

Why is a golf ball spinning?
A spinning golf ball is a good thing because the rapid spin provides aerodynamic lift, causing a spinning ball to travel higher and farther than one with no spin at all. The spinning ball is also less influenced by small gusts of wind, making for a more predictable shot. One of the other features you will notice on the face of a golf club, ...
How does a golf ball spin?
In the 450 millionths of a second that the ball and club are in contact the ball does several things. First, it deforms quite a bit, flattening against the face of the club. As the ball begins to rebound to its normal globe shape, it starts to slide up the club face. Finally, just before it leaves the club, the ball returns to its familiar shape and begins to roll up the face. By the time the ball has left the club face, it is spinning quite rapidly. According to the USGA, a ball hit by a wood or one of the longer irons (3 to 5) will be spinning at approximately 3,600 RPM when it leaves the club. The same ball struck by a pitching wedge will spin at nearly 6,000 RPM when it leaves the club.
Why do golf clubs have grooves?
First, they provide just a bit of "bite" for the golf ball as it's sliding up the face, helping it to spin more rapidly. Next, if grass is trapped between the ball and club at impact , the water in the grass will be squeezed out by the nearly 3,000 pounds of force generated by the average swing . Like the tread on an automobile tire, the grooves on the club face give the water somewhere to go so that the ball doesn't skid up the face without spinning.
How fast does a golf ball spin when hit by a wood?
According to the USGA, a ball hit by a wood or one of the longer irons (3 to 5) will be spinning at approximately 3,600 RPM when it leaves the club.
What does the number on a golf club mean?
The number is related to the angle at which the face slopes back from vertical when the club is held in its normal position facing the ball. A higher number for the club represents a greater degree of slope away from vertical, generally resulting in a higher, shorter shot. There are some slight variations between manufacturers, but the club numbers and their related slopes generally look like this.
What are the parts of a golf club?
The head of the golf club has several parts: the hosel, where the head connects to the shaft; the face, which actually strikes the ball; the sole , which is the part closest to the ground; and the back, which is on the side opposite the face.
How did golf differ from other games?
Golf differed from other contemporary stick-and-ball games in two ways: One, it was played over an irregular expanse of rugged landscape. And two, it entailed hitting the ball into holes. Its history extends back to the 12th century Scottish monarch David I, who set aside swaths of worthless linksland (rough landscapes of sand, grass and water where rivers meet the sea) for public use, beginning with a sleepy fishing village called St. Andrews. These land allotments continued for centuries, expanding to incorporate the Clyde and Forth estuaries and areas beyond.

Why do putters work?
Putters have a relatively simple job: to strike the golf ball with a face perpendicular to the path of a gentle swing and cause the ball to roll along the ground until it falls into a hole. Twisting is still a concern with off-center hits, but a putter is designed to transfer far less energy to the ball than either irons or woods. It's interesting, then, to note the incredible array of shapes taken by the heads of putters -- blocks, blades, short, long, thick, thin, etc., and the various patterns of lines found on the faces. So why is there such variation in a club designed for such a simple task? Because the mechanical simplicity of putting places most of the pressure on the golfer's mental processes, where there is room for far more variation than in any golf swing.
Why do you need a stiff shaft for a golf swing?

Also, applying physics to football leads to better and safer equipment, affects the rules of the sport , improves athletic performance, and enhances our connection to the game.
How does a field goal move?
When the ball leaves the punter's foot, it is moving with a given velocity (speed plus angle of direction) depending upon the force with which he kicks the ball. The ball moves in two directions, horizontally and vertically. Because the ball was launched at an angle, the velocity is divided into two pieces: a horizontal component and a vertical component. How fast the ball goes in the horizontal direction and how fast the ball goes in the vertical direction depend upon the angle of the kick. If the ball is kicked at a steep angle, then it will have more velocity in the vertical direction than in the horizontal direction -- the ball will go high, have a long hang-time, but travel a short distance. But if the ball is kicked at a shallow angle, it will have more velocity in the horizontal direction than in the vertical direction -- the ball will not go very high, will have a short hang-time, but will travel a far distance. The punter must decide on the best angle in view of his field position. These same factors influence a pass or field goal. However, a field goal kicker has a more difficult job because the ball often reaches its peak height before it reaches the uprights.
How does a punter control the speed of a football?
When a punter kicks a football, he can control three factors: The velocity or speed at which the ball leaves his foot. The angle of the kick. The rotation of the football. The rotation of the ball -- spiral or end-over-end -- will influence how the ball slows down in flight, because the ball is affected by air drag.
What determines how far a kick will travel?
The angle of a kick helps determine how far it will travel.
What is the difference between a spiral kick and an end over end kick?
A spiraling kick will have less air drag, will not slow down as much and will be able to stay in the air longer and go farther than an end-over-end kick . The velocity of the ball and the angle of the kick are the major factors that determine: Advertisement. How long the ball will remain in the air (hang-time)
