Put simply: When both the club and ball are dry, there’s more friction on the clubface. The grooves on the clubface grab the golf ball more and impart more backspin. When the clubface is more wet, there’s less friction, so the ball slides up the clubface.

What is static friction in golf?
Static friction is what keeps the ball in place. While setting your golf ball on the tee, static friction is what keeps it there. If there weren't any static friction then the ball would roll of the tee, and it'd be extremely hard to hit the ball! To overcome the static friction on the ball, you must apply enough force in your swing.
How does rolling friction work in golf?
Rolling friction is used while on the green, or after hitting your ball. If your ball doesn't make it in the air, than it rolls on the grass and eventually comes to a stop. That is by the help of rolling friction. Rolling friction is a giant part on the green. After putting your ball, the golf ball rolls in the direction you hit it to.
What type of friction keeps the golf ball in place?
This pressure around the ball is air resistance. While the golf ball is flying through the air, air resistance's and fluid friction's forces are all around it. Static friction is what keeps the ball in place. While setting your golf ball on the tee, static friction is what keeps it there.
Why do golf balls hit the ground faster in the wind?
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. The following is an example of a PGA and LPGA Tour 6-iron shot under different wind conditions.
How does gravity affect a golf ball?
Gravity is always acting on a golf ball when it is in the air or on the ground. To combat this force and make the ball end up in the hole, golfers exert a force on the ball when they swing and hit it.
How is friction used in golf?
Golfers work hard to put just the right amount of backspin on their shots, something that helps the ball stop before it rolls off the green. The brief collision between the club face and the ball produces friction, which unleashes spin.
Does a golf ball have friction?
The friction forces present during the putt include friction between the ball and the club face, and the rolling, static and dynamic (sliding) frictions between the ball and the putting surface.
What forces are acting on a golf ball?
Some of these forces include: gravity, aerodynamic drag, and aerodynamic lift. Each force acts independently on the moving golf ball. For a greater distance to be achieved, one needs to increase the acceleration of the ball by increasing the force with which the ball is struck or swinging the club faster.
What is the physics of golf balls?
2:494:54Science of Golf: Why Golf Balls Have Dimples - YouTubeYouTubeStart of suggested clipEnd of suggested clipThe pressure of the airflow on the ball is decreased creating lift the lift is pronounced due to theMoreThe pressure of the airflow on the ball is decreased creating lift the lift is pronounced due to the dimples on the ball which measure only 15 hundredths of a millimeter.
What is the science behind a golf ball?
As a golf ball travels through the air, wind resistance creates drag, which slows the ball down. The dimples on a golf ball reduce the drag of the air making it possible for the ball to go faster and farther. At the USGA Test Center, scientists created a 70-foot-long tunnel to test golf balls.
How does a golf ball spin?
Spin is basically what makes your golf ball go up in the air. When the air hits the dimples on a golf ball, it create a low pressure area which makes the golf ball go up in the air - lift. The faster the spin, the higher it will go!
Why is golf ball rough?
Rough balls fly through the air more easily than smooth ones. As air flows around a smooth ball, it breaks away from the surface, forming a pocket of swirling currents at the back, like the wake behind a speedboat. This wake creates "drag" on the ball, slowing it down.
Why do golf balls have dimples?
Dimples on a golf ball create a thin turbulent boundary layer of air that clings to the ball's surface. This allows the smoothly flowing air to follow the ball's surface a little farther around the back side of the ball, thereby decreasing the size of the wake.
What force is applied to the ball?
The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion.
What law of motion is hitting a golf ball?
Newton's Third Law of MotionThe impact between a club and the ball produces equal and opposite forces, demonstrating Newton's Third Law of Motion, and also transfers momentum from the club to the ball. "Science of Golf" is produced in partnership with the United States Golf Association and Chevron.
How does golf apply to Newton's second law?
Second Law: Force equals mass times acceleration (f=ma). When a golf club carries an unbalanced force it carries a change in velocity. The change in velocity is acceleration. The greater the force applied to the golf ball the greater the acceleration.
What happens when a golf ball rolls on a surface?
There are several different places in golf where Friction comes into play. As the ball rolls on the green it displays rolling friction. Rolling friction is when an object, in this case a ball, rolls on a surface and the rolling friction is what slows it down.
Why is it so common to hit a golf club in the sand?
It’s more common because players are taught to hit the ball while swinging through all of the sand near the ball to get out of the sand trap.
What is the term for the friction that exists between a stationary object and the surface on which it's resting
When a person putts the ball across the green rolling friction acts on it and slows it down. Static Friction: The ball sitting on the green/fairway/tee. Static friction is the friction that exists between a stationary object and the surface on which it's resting.
What forces are around a golf ball?
While the golf ball is flying through the air, air resistance's and fluid friction's forces are all around it.
What happens if your golf ball doesn't make it in the air?
If your ball doesn't make it in the air, than it rolls on the grass and eventually comes to a stop. That is by the help of rolling friction. Rolling friction is a giant part on the green. After putting your ball, the golf ball rolls in the direction you hit it to. It eventually comes to a stop, or rolls into the pin.
What is the function of the dimples in a golf ball?
Fluid Friction is used while the golf ball is in the air. The dimples in the golf ball make the ball fly further, and help with the pressure of the air around it. This pressure around the ball is air resistance.
What happens if there is no static friction?
If there weren't any static friction then the ball would roll of the tee, and it'd be extremely hard to hit the ball! To overcome the static friction on the ball, you must apply enough force in your swing.
What is sliding friction?
Sliding friction is when two objects slide past each other. Sliding friction isn't used much in golf, but it is used when the ball makes contact with the ground and then slides to a stop. If playback doesn't begin shortly, try restarting your device.
Why do putts break?
As short-game guru Stan Utley explains, "Putts break because of gravity. ". If there's a mountain to your right and a lake to your left, the land will typically slope from right to left—and that's the way a putt will tend to break.
Does a hole in golf ball count as ground under repair?
The hole, even if it's unmarked, counts as ground under repair. But because your ball was not in or touching the hole— it sounds as if the area around the hole was not marked as ground under repair—you have to play this one as it lies. You would get free relief if the hole affected your normal stance or swing.
Can you mark your ball in golf?
Only you or an authorized person (e.g., a caddie) can mark your ball, according to the rules . There's a one-stroke penalty for moving another player's ball or mark in match play. In stroke play, there is no penalty. Submit your burning questions here: [email protected] or on Twitter @GolfDigest.
Abstract
The putting of a golf ball requires control of the speed and direction and an understanding of the interaction between the ball and the putting green by the golfer. The putt can involve a combination of the ball flying over, skidding across, and rolling on the putting green.

Why do golf balls have dimples?
The dimple pattern on the ball facilitates this control . The dimples reduce the drag on the surface of the ball, causing it to stay in the air longer. If you're an accomplished amateur with a low handicap you'll probably prefer a golf ball that gives you more control.
What are the limitations of the USGA?
The USGA puts limitations on the size, weight, speed and the potential distance of golf balls. The initial velocity and distance as tested using USGA equipment is limited, and the standards are updated to reflect the currently available equipment.

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.
What can affect the bounce and roll of a car?
A great example of how wind affects bounce and roll was seen at the World Long Drive Championship a few years ago.
Do you need a trackman to play golf?
The good news is that you don’t need to play with a professional golfer to fully understand the effects of wind on the golf ball. Chances are that there’s a Trackman somewhere near you, and it measures the entire ball flight to help golfers understand what wind does to their shots.
What happens when you hit a golf ball into the wind?
If you are faced with an into the wind shot the wind will push the ball back towards you and it will go shorter than what it normally would.
How does wind affect golf ball distance?
The decrease in distance that the ball will travel as a result of the wind will depend on the strength of the wind. In addition to the ball traveling shorter through the air, the ball will also tend to roll less once it hits the ground or putting surface. If you are faced with an into the wind shot it is important to calculate for both ...
What is the difference between a crisp shot and a spinny off center strike?
Crisp shots with optimal spin rates tend to be less affected by the wind than a spinny off-center strike. This might sound very technical but the long and short of it is that the better you hit the golf ball the less impact the wind will have on it as it flies through the air. If the wind wasn’t hard enough to judge how ...
What happens when you hit a downwind shot?
If you are faced with a downwind shot the wind will push the ball to go further than what it normally would. The additional distance that the ball will travel as a result of the wind will depend on the strength of the wind. In addition to the ball traveling further through the air, the ball will also tend to roll more once it hits ...
What direction does the wind push the golf ball?
If you are faced with a crosswind shot the wind will push the ball away from your target in the direction of the wind, thus with a right to left wind the wind will push your golf ball to the left of your target and vice versa.
How far does a golf ball travel in wind?
Unfortunately, there is no rule of thumb that says for everyone 10 mph of wind the ball will travel 10 yards shorter or longer depending on the wind direction. On a windy day, it is very important to take note of how far your golf ball travels on both the practice tee and on your first couple of holes on the golf course.
What happens if you hit a fade in the right to left wind?
If you were to hit a fade into a right to left wind the wind will knock the ball down and it will fly shorter. The opposite will be true if you were to hit a draw, with a draw the right to left wind will carry the golf ball to fly further than normal.
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 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 ...
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.
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 ...
Challenge of Putting
- For the golfer sloping greens add to the challenge of putting. Each green has its own personality, and it is up to you to be able to read its characteristics. To do this it is helpful to know the forces that cause your ball to breaka certain way.
Gravity
- Gravity (G) is the single most important force that acts on how your ball rolls on a inclined surface. It is made up of two components. The first is the force that pulls everything towards the centre of the Earth. For example, on a flat green it merely holds your ball against the surface, but doesn't move it. However, on a slope there is a sidehill component of gravity that works to move …
Friction
- Friction (F) is the resistance an object encounters in moving over another object. It is the force that opposes motion. For example, when you putt your ball on a flat and level green, it will roll until the energy imparted by your stroke is overcome by friction. Slower greenshave greater friction than faster greens and stop your ball quicker. When you putt against the grain there is more resi…
Forward Momentum
- Forward Momentum (FM) takes place when your putter makes contact with the ball. The amount of forward momentum is usually determined by the length of your backstroke. As there is no such thing as perpetual motion your ball - even if you putted on a sheet of flat glass - would eventually come to a stop.
Motion
- Motion (M) occurs whenever the ball moves, either as a result of gravity or a combination of gravity and forward momentum. Your ball will stop moving when friction finally is greater than both the forces of gravity and forward momentum combined.
Sloping Greens
- The skill of putting on sloping greens comes from your ability to factor in the various forces that act on your ball on its way to the hole. In science the roll of the ball can be explained by the laws of physics. From a practical point of view it is judging the degree and direction of the slope (gravity), the speed of the green surface (friction), and the amount of force (forward momentum…
