Do golf balls have dents?
Most golf balls have between 300 and 500 dimples, which have an average depth of about 0.010 inch. The lift and drag forces on a golf ball are very sensitive to dimple depth: a depth change of 0.001 inch can produce a radical change to the ball's trajectory and the overall distance it can fly.

Why do cars not have dimples in golf balls?
The dimples in a golf ball promote an earlier transition to turbulent flow and thus reduce the pressure drag of the golf ball, so it can fly further. In a car, the size is large enough to develop a turbulent boundary layer early on. Dimples would not help, but increase drag slightly.
Do golf balls always have dimples?
Like many inventions, the golf ball dimple was discovered accidentally. By 1930, the dimpled golf ball had become the standard in golfing. A golf ball with dimples can travel almost twice as far as a smooth golf ball.
Why is a golf hole 4.25 inches?
Four-and-a-quarter inches in diameter. R&A ADOPTS 4.25-INCH HOLE SIZE That first hole-cutting implement utilized a cutting tool that was, you guessed it, 4.25 inches in diameter. The folks running the R&A apparently liked that size and so adopted it in their rules for 1891.
Why is a golf ball white?
It was a bright color and was a good alternative compared to the natural brown of the feathery balls. It is not as if high-intensity yellows and neons were available options, so for hundreds of years, white was the standard color.
Do dimples make a car faster?
Adam Savage and Jamie Hyneman at Mythbusters tested 3 Ford Taurus cars: one normal car, one car covered in smooth clay, and one covered in clay with 1,082 dimples scooped out. Sure enough, while the smooth cars could drive 26 miles on a gallon of gas, the dimpled car drove almost 30 miles!
Do golf ball dimples reduce drag?
Golf ball dimples reduce drag by creating a turbulent boundary layer flow around the ball. The boundary layer is defined as a thin layer of fluid dragged by the ball. By creating this turbulent boundary layer, the separation point decreases.
What are the dimples in a golf ball called?
What Are Dimples On A Golf Ball Called? In most cases, golf ball dimples are simply referred to as dimples. However, there are some instances when they will be called indentations or more thoroughly referred to as the golf ball dimples pattern.
What makes a golf ball Illegal?
Legal golf balls can't be smaller than 1.68 inches in diameter. The Polara balls have a diameter of 1.68 inches (the same size as normal). If you have a smaller ball, you'll have less drag and that should give you more distance.What Is The Longest Illegal Golf Ball?https://outofboundsgolf.com › what-is-the-longest-illegal-...https://outofboundsgolf.com › what-is-the-longest-illegal-...

Who invented golf ball dimples?
Coburn Haskell introduced the one-piece rubber cored golf ball encased in a gutta percha sphere. Then in 1905 William Taylor applied the dimple pattern to a Haskell golf ball, thus giving rise to the modern golf ball as we know it today.Golf Balls - The Story Behind The Dimpleshttps://golfbug.com.au › blogs › news › golf-balls-the-sto...https://golfbug.com.au › blogs › news › golf-balls-the-sto...
When did golf balls start having dimples?
In 1905, an English manufacturer named William Taylor registered a patent for a golf ball dimple design. Before long, all golf balls featured dimples that would be more or less recognizable today.
How many dimples are there on a golf ball?
Most modern golf balls have about 300–500 dimples, though there have been balls with more than 1000 dimples. The record holder was a ball with 1,070 dimples—414 larger ones (in four different sizes) and 656 pinhead-sized ones.
How many dimples are on a British golf ball?
330On 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 golf sticks called?
A golf club is a club used to hit a golf ball in a game of golf. Each club is composed of a shaft with a grip and a club head.
Can You Get Dents Out Of Golf Clubs?
You can remove dents from golf clubs, but results may vary on how big the dent is or where it can be found on your golf club. Dent repair can be costly, and in some instances, purchasing a new club may be more worthwhile than a repair.
How Do You Fix A Dent In A Golf Club?
To avoid causing more damage to your golf clubs, it’s wise to employ a professional to fix your clubhead dents for you. Professionals will smoothen the dent by drilling into your golf club or shaving down the head on your irons and evening the discrepancies on the club.

Why do dimples reduce drag?
When a ball is rough (has etchings or dimples) the airflow along the boundary of the ball is turbulent, causing a buffer of turbulent air between the ball and the smooth air causing the drag. This turbulent layer clings to the surface of the dimpled ball and allows the smooth flowing air to wrap around the ball better, hence significantly decreasing the size of the wake. Hence, dimples manage to reduce drag by half as compared to a smooth ball.
How do dimples affect lift?
The lower region is of higher pressure compared to the upper, which leads to an upward force. The dimples, increase this imbalance, increasing the lift force.
What is the difference between drag and lift?
Drag is the force that always opposed the direction of motion whereas lift acts perpendicular to the motion (usually upwards in the case of a golf ball). A moving ball has a high-pressure area on its front side. The air flows smoothly along the boundary of a smooth ball, causing drag. It also leaves behind a wake region where the airflow is turbulent. The size of the wake also increases the amount of drag.
How many versions of Titleist Pro V1 are there?
A good example of this is the Titleist Pro V1. There are two versions of this ball available at the retail level (not including yellow)…the Pro V1 and Pro V1x. However, there are 14 versions of this ball on the USGA conforming list.
What is the purpose of dimples in golf?
The purpose of the dimples is to increase aerodynamic lift using something called the Magnus effect. A golf ball has between about 1600 and 9000 rpm of backspin - depending on the club and the golfer and the shot being played. This backspin drags air around the top of the golf ball. Interaction between this dragging and the motion of the ball through the air towards its target directs the airflow downwards behind the ball (more towards the ground). The reaction to this downward force on the air is to
Why do golf clubs have dimples?
The purpose of the dimples is to increase aerodynamic lift using something called the Magnus effect. A golf ball has between about 1600 and 9000 rpm of backspin - depending on the club and the golfer and the shot being played. This backspin drags air around the top of the golf ball. Interaction between this dragging and the motion of the ball through the air towards its target directs the airflow downwards behind the ball (more towards the ground). The reaction to this downward force on the air is to provide an upward aerodynamic lift force on the ball (the Magnus effect). The purpose of the dimples is to “drag” much more of the air around so it can be directed downwards. This lift causes the ball to fly much much further (especially when hit with a low lofted club) because it stays airborne much longer. Without the dimples the smooth surface drags much less air around the ball, and the lift is barely there.
What is the difference between the top line and the middle line?
The top line (“current ball”) is the ball the player normally uses, or in your case it could even be a range ball. The middle line (“ideal”) is the optimum launch conditions based on the clubhead speed recorded when hitting shots with the current ball. In this example, if everything was perfect this player has the potential to hit his driver 256 yds. with his clubhead speed. By changing to a ball with a softer core, higher launch and less spin, all of his launch numbers got better (“recommended ball”) which made his trajectory more efficient and resulted in 7 yards more distance off the driver. It’s roughly half that much with the irons, so on a typical par 4 that’s a 10–11 yard gain. Remember, that is for this example…the amount of difference will vary from player-to-player.

Why Do Most Golfers Prefer White Golf Balls?
As a general rule golfers use white golf balls because that is what they are familiar with. Consistency is key in golf whether that be a swing or putting stroke and the colour of the golf ball they choose is no different. Striking and watching the same coloured golf ball becomes second nature and to change alters the familiar.

Is a golf ball smooth or turbulent?
A golf ball, which is small but fast, is delicately balanced between these two behaviours. A smooth golf ball tends to have that smooth kind of boundary layer which gives high drag. However, dimples disturb the flow enough to make the boundary layer turbulent, reducing the drag and allowing you to hit the ball further. For a car or train, which are quite fast and very large compared to a golf ball, the boundary layer is turbulent anyway so dimples have no effect.
