Indentation of the ball at rest on the green Once the ball starts the roll motion without slip on the green with the initial velocity, the ball travels a certain distance without slip and then stops. In order to stop the roll of ball, we should introduce a resistance moment between the ball and the green surface.
Full Answer
What happens when a ball rolls on the ground?
For example, when the ball rolls on the ground, the force of friction acts between the surface of the ball and the surface of the ground. The irregularities between the two surfaces lock into each other and thus, stop the ball from moving any further unless it is moved by an external force.
What happens if you hit a golf ball over the water?
In one case in particular you might find yourself getting ready to hit your next golf shot over water. After hitting the golf shot over the water successfully, it lands on the green or the grass short of the green which happens to slope down towards the water, sending your ball rolling backwards into a water hazard.
How do you stop a ball from rolling on the Green?

In order to stop the roll of ball, we should introduce a resistance moment between the ball and the green surface.
How to hit a golf ball in the rough?
The extra power is required because a ball in the rough will be slowed by the thick grass as it gets airborne. Choke down on the club like a baseball batter chokes up on the bat. This means leaving space between the top of the club and the top hand of your grip. Choking down will create stability when you hit the ball.
What force causes a rolling ball to stop?
frictionThe force in question is friction. A rolling ball stops rolling for the same basic reason that if you slide a book across the floor, it will eventually stop: there is friction between the floor and the book. There is also friction between the ground and part of the ball that touches the ground as it rolls.
What could cause a ball rolling on the grass to stop?
When you roll a ball on the ground, the electrons in the atoms on the surface of the ground push against the electrons in the atoms on the surface of your ball that is touching the ground. A rolling ball stops because the surface on which it rolls resists its motion. A rolling ball stops because of friction.
What forces act on a rolling ball?
The forces on a rolling ball include a horizontal friction force, F , and the normal reaction force, N , acting a distance S ahead of the center of the ball.
How do you stop a ball from rolling?
A rolling ball ceases when its motion is resisted by the surface on which it moves. A rolling ball, due to friction, ceases. Hence, option B is correct. Note:The force of friction works between the ball's surface and the surface of the earth as the ball bounces on the ground.
Why does a ball rolling along the ground stop a moving bicycle?
For example, when the ball rolls on the ground, the force of friction acts between the surface of the ball and the surface of the ground. The irregularities between the two surfaces lock into each other and thus, stop the ball from moving any further unless it is moved by an external force.
Which of the following forces causes objects to slow down and eventually stop?
It was usually friction that made moving objects slow down and eventually come to a stop. To keep an object moving, a force had to be applied to overcome the effects of friction. If friction could be removed, an object in motion would continue to move in a straight line with constant speed.
What type of friction causes a ball to stay motionless on a flat surface?
Static friction acts on objects when they are resting on a surface.
What causes friction?
Friction is caused due to the irregularities on the two surfaces in contact. Even the smoothest surfaces have minute irregularities in them and these irregularities of the two surfaces interlock into each other and create friction.
What does it mean when a golf ball is flying?
This will cause a "flyer" type of ball flight that has little to no spin.
Is hitting the greens important?
Being able to hit greens is important. But, being able to keep the ball on the green is even more crucial to shooting good scores. So, make sure you check your setup and swing to see if you are doing any of the things I've mentioned in today's video.
Why is my golf ball so obscured?
The golf ball may also be partially or totally obscured by the thick grass; that lack of a visible target may cause you to mishit. Knowing how to get under the ball and generate extra power may help you maneuver out of trouble.
How to catch the ball cleanly?
Take a three-quarter backswing, keeping weight on your front foot . The goal is the catch the ball cleanly. Take a V-shaped swing when the ball is buried to try to loft the ball onto the fairway. You may not get a lot of distance but you are getting out of trouble and may save a few shots in the process.
What happens if you don't trap a lot of grass?
If you don't trap a lot of grass when the club impacts the ball, you may catch the ball cleanly and hit a flier: a line drive that runs fast upon landing. Trapping a lot of grass in the rough results in a slower swing speed, which affects distance. The lie of the ball will determine the amount of backswing and club speed you create.
How to get a ball to lift?
Play the ball in the middle of your stance. This allows you to swing down on the ball and pinch it, causing it to lift.
What is stopping a golf ball on the green?
In reality, stopping a ball on the green is a relatively simple combination of technique, strike and technology. Professionals on tour create a greater amount ...
How to stop a golf ball from going up the green?
The simplest option for bringing your ball to a stop on the green is to use plenty of loft on your shot. If you send the ball high up into the sky as it travels toward the hole, it is going to come down on a steep angle – and it won't have much forward momentum left after it lands. This kind of shot will likely take one or two bounces, move only a bit forward, and then stop completely. Not only is this an effective way to stop the ball, but it is also helpful in terms of getting over any hazards which may be guarding the front of the green. You can take that pesky slope at the front of the putting surface out of play by simply flying the ball well onto the green before bringing it down with a thud. There is a reason you see so many professional players hitting the golf ball way up into the sky – it is an extremely effective way to play the game.
What is the importance of clean contact in golf?
When it comes to spin, nothing is more important than clean contact. If you catch the ball cleanly at the point of contact, you will maximize the amount of backspin that is produced. Many amateur golfers struggle to achieve a clean hit, instead hitting the ball a little fat or thin on most of their shots.
How to raise the ball flight?
Move your ball position slightly forward. This is one of the quickest things you can do to raise the height of your ball flight pattern. Instead of playing the ball from the middle of your stance, for instance, move the ball a couple inches to the left as you are looking down from address. This is going to allow you to contact the ball while using more of the loft on the club, leading to a higher flight. If you are going to get the full benefit from this adjustment, however, you need to make sure to keep your swing mechanics exactly the same. If you slide to the left in the downswing to get over to the ball, the effect will be lost and you will hit a lower-than-desired shot. Once you move the ball position to the new spot, go ahead and make your standard swing while using rotation rather than lateral motion. If executed correctly, you should see the ball immediately begin to fly higher than with your previous technique.
Why do professional golfers have a greater amount of back spin than handicap golfers?
Professionals on tour create a greater amount of back spin than many handicap golfers because of the impact conditions they create with the shorter irons and wedges. This mainly consists of a high club head speed and downward strike on to the ball.
How to fade a golf ball?
You can use this tip in conjunction with the previous tip for a powerful effect. By standing just a bit closer to the ball at address, you will cause your swing plane to become more upright – meaning you will be more likely to hit a slight fade. Since a fade is almost always going to fly higher than a draw, you will have elevated your ball flight without doing anything else to your technique. It is important to keep your ball position toward your left foot when using this tip, as standing close and keeping the ball back in your stance can lead to ugly results.
What is the job of a golfer?
One of the most important jobs you have as a golfer is bringing your ball to a stop in a timely manner on the green. Of course, you are always trying to hit the greens with your approach shots, as hitting the green is going to leave you with a birdie attempt.
When your ball is at a neutral position on the ground, your club needs to dig into the ground?
When your ball is at a neutral position on the ground, your club needs to dig into the ground in order to achieve contact at the true loft of your club. This is one of the many counter-intuitive motions in golf, many of which take time to learn.
Why is my ball not rolling across the ground?
In simplest terms, in order to get the ball up into the air — and not rolling across the ground — is to hit down into the dirt. (GETTY) If that’s not happening, there may be a few reasons why. Here are some of the most common I see: 1. Bad Posture. Good posture is the basis for solid contact.
How to throw a golf club toward the ground?
It can be helpful to practice this by placing a ball in your right hand, from your golf posture. Allow the elbow to fold as it would in your backswing and then throw the ball so that it hits the ground.
What ruins a golf swing?
Nothing ruins a great golf swing like a loss of balance. Assuming you’re in a good set up to start, it only takes a small loss of balance to cause you to top the ball. A good check of balance is holding your finish until your golf ball lands.
How to maintain a good path in backswing?
It’s possible to have a proper path in your backswing without sacrificing width. Keeping your hands away from your sternum can help to maintain the width of your backswing, making it easier to brush the grass. One of my favorite drills for feeling this is to hold your lead wrist with your trail hand. From here, make your backswing without a club and feel your trail arm pull your lead arm wide. While you practice, be sure to keep your lead underarm close to your body to maintain a good path and width.
How to get the ball down to the ground?
1. Bad Posture. Good posture is the basis for solid contact. Bowing forward from your hips so that your hands can hang below your shoulders can put you in balance and also get the club down to the ground. Too much knee flex or squatting can often make it extremely difficult to get the club down into the turf, and therefore get the ball into the air.
What happens if you stand too far away from the ball?
If you stand too far away from the ball at address, it’s almost difficult not to top the ball without a heroic move. Reaching for the ball — where your arms often get into a diagonal position — will often lead to a thin shot or a top.
Abstract
The aim of this work is to analyze the landing effect of a golf ball based on physics. The effect of the launch speed, impact angle, backspin, and green firmness on the run for a variety of golf shots is considered. We analyze green dynamics using stimpmeter and Werner and Greig’s empirical equations.

How fast is the golf ball off the bottom of the ramp?
Arthur Weber has written for the USGA Green Section an article entitled Green Speed Physics (pdf document) that calculates a speed of the golf ball off the bottom of the ramp of 95.5 inches per second.
How far off the ground can you raise a bowling ball?
If you want to raise a bowling ball five feet off the ground, its a lot easier to roll it up a gently sloped ramp than it is to hoist it straight up, and carrying a suitcase up a flight of stairs is harder on steep stairs than on a long, more gently sloped flight of stairs.
What is PE in golf ball?
PE = W*H. The Potential Energy (PE) is the ENERGY stored in the golf ball's WEIGHT (W) by raising it higher than it is on the ground a certain HEIGHT (H). For the Stimpmeter and a golf ball, the numbers are PE = 1.62 ounces (oz) * 10.5 inches. Thus PE = 1.62 * 10.5 = 17.01 in-oz of ENERGY with the Stimpmeter raised.
What is the kinetic energy of the ball off the bottom of the ramp?
The Kinetic Energy of the ball off the bottom of the ramp is the PE reduced by part of the ANGLE of the ramp's tilt.
How to calculate the time it takes to roll down a ramp?
To figure how long in TIME it takes to roll down the ramp, which is always the same, the formula is simply DISTANCE = SPEED * TIME. Here, SPEED is the average VELOCITY while rolling down the ramp. Since the ball starts at 0 inches per second velocity in the notch, and smoothly accelerates to a peak VELOCITY at the bottom or end of the roll off the ramp of 86.9 inches per second, the average velocity or SPEED is one half 86.9, or 43.45 inches per second. The DISTANCE is 30 inches. So the TIME = DISTANCE / SPEED, or T = 30 in / 43.45 in/s, for a total roll time of 0.69 seconds. If you silently mouthed "one mississippi" after the ball starts rolling, then ball would exit the bottom of the ramp after about "one missip..."
Is a frictionless block faster than a ball?
But if you compare a frictionless block sliding down a ramp and a ball rolling down the same ramp, the translational acceleration of the block is faster than that of the ball, and the resulting velocity at the bottom of the ramp is accordingly faster for the block than the ball.
Does rolling coefficient depend on green surface?
That's part of the problem. I would say that what he calls "rolling coefficient" would strongly depend on the particular green surface and perhaps speed as well. Seems like a bit of a bogus model to me.
Where to drop golf ball behind hazard?
Or you can drop the golf ball behind the hazard, keeping the point where it crossed the margin in line with the flagstick on the green. Picture drawing a line from where the ball crossed into the water and the flagstick.
What happens when you hit a golf shot over the water?
After hitting the golf shot over the water successfully, it lands on the green or the grass short of the green which happens to slope down towards the water, sending your ball rolling backwards into a water hazard.
Can you drop a ball on the green side of the water?
In some cases of the lateral hazards (red stakes / lines) and yellow stake / line hazards, your ball may be able to be dropped on the putting green size of the water hazard. This only happens if it still meets the rule outlines above.
