Do grooves on a golf ball affect the spin?
The intuition is correct that the more “grab” on the ball at the point of impact, the more it will spin. Many people don't know that a club face with no grooves would actually put more spin on the ball. The smooth face would have more surface area to come in contact with the ball.
What is the volume of a golf ball?
In general, USGA rules allow a ball to have a diameter of 1.68 inches, corresponding to a volume of about 2.48 cubic inches (40.68 cm3). The number and depth of dimples will affect its actual volume as well.
How does humidity affect golf ball distance?
Humidity has a significant effect on golf ball distance, too. The higher the humidity, the longer the ball flies. You can feel humid air more, but water weighs less than the nitrogen and oxygen molecules that make up dry air.
How do club faces affect the spin of the ball?
The intuition is correct that the more “grab” on the ball at the point of impact, the more it will spin. Many people don't know that a club face with no grooves would actually put more spin on the ball. The smooth face would have more surface area to come in contact with the ball. More surface area means more friction and therefore more ball spin.
Does the amount of dimples on a golf ball matter?
The number of golf ball dimples is less important than the shape and depth of the dimples. The number of dimples can affect drag, so it is important to not have too many dimples. Between 330 and 400 dimples is the optimum number. More dimples mean more focussed control over the ball trajectory.
What are the small ridges of a golf ball called?
Golf balls can have dimples that are deep, shallow, large or small. Some golf balls have different sizes of dimples on the same ball. Dimples come in all different shapes, including circles, ovals, teardrops and even hexagons like a soccer ball.
Do dimples on a golf ball decrease surface drag?
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 will a dimpled golf ball travel further than a smooth golf ball?
The dimples in golf balls create turbulence (that means mixed airflow!) which, if done right, reduces drag, making it go farther.
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.
What do you do with old golf balls?

How many dimples are on a Pro V1 golf ball?
388 dimplesThe new Pro V1 has 388 dimples, and the new Pro V1x has 348 (both in a tetrahedral pattern), marking the first time the dimple counts have changed since 2011. Dimple patterns, however, are far more than simply the number of them.
How much do dimples reduce drag?
A smooth golf ball hit by a professional golfer would travel only about half as far as a golf ball with dimples does. Most golf balls have between 300 and 500 dimples, which have an average depth of about 0.010 inch.

Why are most golf balls white?
In the 17th century leather golf balls were painted white with readily available chalk or lead pigment to ensure they could be spotted amongst the green grass. So why could they soon fall out of favour? White has proven to be an excellent all-round colour for a range of golfing conditions.
Why are there 336 dimples on a 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 are the lines on a golf ball for?
You might have seen golfers marking their ball with a pen on the greens, particularly before a tricky putt. The simple purpose of this is to help with aim and alignment as they look to putt through the ball in a straight manner.
Who put dimples on a golf ball?
In the early 1900s, another inventor found that indentations in golf balls performed far better than raised protrusions. 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 divots are there on a golf ball?
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.

Because these dimples have caused. Some low level turbulence.
How does the golf ball curve after driving?
Depending on conditions, this effect can be demonstrated clearly in the moments immediately after driving a golf ball, where you can see the trajectory of the ball curve upwards due to the lift generated .
What happens when you drive a golf ball?
When you drive a golf ball, dimpled or otherwise; it has backspin. This backspin results in the top of the golf ball moving slower relative to the air around it since they’re both traveling in the same direction. As such, there is less drag on the air that goes over the ball, creating an area of low pressure above it.
Why do golf balls have dimples?
Why Golf Balls Have Dimples. Golf balls have dimples because the turbulent flow of air they create increases Magnus lift, a lifting force which affects rotating objects while traveling through the air. It’s the same force that makes a soccer ball swerve when sliced, or a tennis ball dip during a chip shot.
Why did golfers put dimples on their golf balls?
However, until the 1900s, it was widely believed that the protrusions were the reason behind the improved range and stability.
What happens to the air that goes over the ball?
As such, there is less drag on the air that goes over the ball, creating an area of low pressure above it. Air passing over this area stays hugged tight to the ball longer, following the curve of the ball and separating later. The opposite is happening on the underside of the ball.
What does it mean when air is being pushed under a ball?
Air passing over this area separates from the curve of the ball much earlier than the air flowing above the ball. The combination of these different pressure zones and resulting drag means that more air is being pushed under the ball than above it; pushing the ball up. The ball is using drag to its advantage.
What would happen if the ball didn't have dimples?
Without the dimples, the ball would travel in a much more parabolic trajectory. It would rise to its maximum height sooner and come back down to the green.
Why Do Golf Balls Have Dimples?
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. Essentially, golfers would have little hope controlling a smooth golf ball.
How Big Are Dimples on Golf Balls?
The size of golf ball dimples are most frequently measured by their depth. The average depth of a golf ball dimple is roughly 0.010 inch. The circumference of dimples also varies from model to model. While most dimples are spherical in shape, they don’t have to be. Callaway’s HX ball has hexagon-shaped dimples, for example.
How Do I Know Which Golf Ball Dimple Patters Are Right for Me?
Additionally, the size of golf ball dimples and the dimple pattern on golf balls is specific to each model.
How Much Does a Golf Ball Weigh?
Golf ball weights varied dramatically for much of the game’s history. With older golf ball designs dating back hundreds of years, the most consistent thing about their weights, shapes and sizes was the inconsistency.
What happens if you don't have dimples on your golf ball?
The one with no dimples at all produced a low-flying knuckeball. “The dimples help to create lift,” Nardacci told Wall. “Once the ball leaves the clubhead, the only thing acting on the golf ball are aerodynamic forces of gravity.
How many dimples does a Titleist Pro V1 have?
For example, the 2017/18 model of the popular Titleist Pro V1 has 352 dimples on it, while Titleist’s other flagship ball from the same year, the Pro V1x, has 328 dimples. For one manufacturer, the answer to how many dimples on a golf ball was a whopping 1,070, which happens to be the record for the most dimples on a golf ball.
What happens when a ball spins backwards?
When a ball spins backwards, the air pressure underneath it is greater than above it, so the ball rises in the air. Dimples magnify this effect, contributing as much as 50% to the total lift.
Why do golf clubs have grooves?
Golf club grooves have the exact same function as the treads on a tire. They allow water and debris to move away from the ball’s point of contact to provide cleaner contact with better control. Striking a ball from the rough can be unpredictable when there is a lot of debris between your club and the ball. Grooves help tremendously to make these shots more predictable.
What is the difference between a grooveless and a smooth face golf club?
The smooth face would have more surface area to come in contact with the ball. More surface area means more friction and therefore more ball spin. From a perfectly clean lie with no obstructions between the ball and the club face, a grooveless club will always out spin a club with grooves.
Why are slick tires better than treaded tires?
Slick rubber car tires have no problem gripping the road in dry conditions. In fact, they will grip better than treaded tires due to the bigger area of contact. Once the road becomes wet, bare tires or "slicks" as they're known, completely lose their benefit. These tires will hydroplane and slide out because the water under the tire has no place to escape to. The thin layer of water under the tire almost completely removes the friction that was keeping it gripped to the road. Treaded tires however allow water and other debris to escape the contact area, making the tire very grippy in wet conditions. Now, back to golf clubs…
Why did the PGA use the U groove?
In turn, because the rough shots were so “easy”, the PGA took action .
What is a check in golf?
They can land the ball straight on the green and have it either stop dead, or roll back, leaving them with a perfect uphill putt. In golf jargon, this roll back is called “check”. Many players mistakenly attribute the ball “checking-up” to the grooves on the club face. They think that the grooves must grab the ball at impact and cause it to spin. What they don’t realize is that a club face with no grooves would actually produce more spin in perfect conditions! Let me explain…
What happens when you shoot from the rough?
But when you're shooting from the rough, grooves make a massive difference. When a player strikes a ball from the rough, there is lots of debris between their club and the ball: soil, sand, grass, and water are the main culprits.
Does a smooth face golf ball have more surface area?
The intuition is correct that the more “grab” on the ball at the point of impact, the more it will spin. Many people don't know that a club face with no grooves would actually put more spin on the ball. The smooth face would have more surface area to come in contact with the ball. More surface area means more friction and therefore more ball spin.
How does wind affect golf ball bounce?
A great example of how wind affects bounce and roll was seen at the World Long Drive Championship a few years ago. The wind was blowing from behind the players and they were hitting drives that were going 450 yards or more. Yes, they were seeing more carry due to the wind, but they were also seeing a lot of bounce and roll. When I looked at the data, I noticed that not only was the landing angle of the ball shallower, but the landing speed of the ball was significantly higher. A normal drive will typically land at around 65-70 mph, but some of these shots were landing at nearly 100 mph. Because the downwind was reducing the amount of drag the golf ball was experiencing, the ball was hitting the ground faster and at a flatter angle.
How fast does a golf ball hit?
A normal drive will typically land at around 65-70 mph, but some of these shots were landing at nearly 100 mph. Because the downwind was reducing the amount of drag the golf ball was experiencing, the ball was hitting the ground faster and at a flatter angle.
Does wind affect shot?
Since there isn’t a hard rule for how wind affects all shots, I would encourage you to find a certified TrackMan professional and play around on a windy day. He or she will be able to use the normalization feature in TrackMan to show you how far the ball would have carried under calm conditions, as well as show you real-time data of what the ball did in the conditions that day.
Which side of the ball will cause the ball to move strongly to the left in the air?
Mud on the right side of the ball will almost always cause the ball to move strongly to the left in the air with a neutral swing
What happens when you strip a drive right down the middle?
It’s never a good feeling when, after you’ve striped a drive right down the middle, you get to your lie only to discover that there’s a large chunk of mud attached to one side of your ball. For years I had heard that mud on the ball causes it to do crazy things in the air, but I was never sure.
Does mud affect the direction of a golf ball?
Mud on the top, front, or back portions of the ball doesn’t necessarily affect direction ( i.e., left or right), but it will cause the ball to carry significantly shorter.
What does spin do to golf balls?
In layman’s terms, they create spin which generates drag and lift force for the golf ball. The ball needs a certain amount of spin and speed to maintain a controlled flight and grooves are one of the critical variables. It’s the complete opposite of the downforce generated by Formula One cars.
How would a wedge perform without any grooves?
A wedge without grooves will generate a flop-shot-like trajectory, only with less control. The ball will effectively slide up the face in both wet and dry conditions. Out of a bunker, however, a wedge with or without grooves will behave in almost exactly the same way.
When do you know if your grooves are worn out?
Watch for fliers. If you start to notice the ball is flying higher and longer, it could be a sign the grooves are going.
Why does my golf ball fly farther?
You can feel humid air more, but water weighs less than the nitrogen and oxygen molecules that make up dry air. So, you're hitting into thinner air, which means the ball goes farther as though a golfer were playing at a higher altitude.
How far can a golf ball travel above sea level?
Altitude, or elevation, and wind have the greatest and most apparent effect on golf ball distance. Every 1,000 feet above sea level a golf course sits, a golfer can expect their ball to travel approximately 2 percent farther.
How far does a golf ball fly?
According to the folks at TrackMan, for every 10 degrees of increase in temperature, the golf ball flies approximately 1.33 to 1.66 yards farther, depending on the club being used. This is because the temperature changes air density, which is ultimately the factor determining how well the golf ball can fly through the air with minimal drag ...
Do weather factors have more effect than a whole club?
All told, these kinds of common weather factors will never have more effect than a whole club.
Does the golf ball fly farther in the summer?
However, the effect heat has on the distance the golf ball travels isn't as much as most golfers, including many professionals, think. If playback doesn 't begin shortly, try ...
