Golf trajectory formula

Use this trajectory calculator to find the flight path of a projectile. Type in three values: velocity, angle and initial height, and in no time you'll find the trajectory formula and its shape.

Keep reading if you want to check the trajectory definition as well as a simple example of calculations. Trajectory, also called a flight path, is the path followed by a moving object under the action of gravity.

Usually, the term is used when we're talking about projectiles or satellites where the regularly repeating trajectory is called an orbit. In an object is thrown for short distances, then a parabola is a good approximation of trajectory shape. And as we know, sine over cosine is a definition of tangent.

So, the final trajectory formula may be expressed as:. If you're interested in different aspects of projectile motion, check out our other dedicated tools to calculate:. Let's check out the trajectory of water from a water fountain:. The critical thing to notice is the possible difference in axes scaling, so the angle may not look like on the chart as it should. Remember that in all calculations, air resistance is neglected.

The ball flies farther at high altitudes: The air is less dense, so there is less friction to slow the orb's forward motion.

At the U. Senior Open in at the Broadmoor in Colorado Springs -- about 6, feet above sea level -- great players found themselves perplexed. Determine the correct yardage from your ball to the green. You may buy a yardage book at some courses to assist you, or you may use the distance markers on the course. Walk off the distance between your ball and yardage marker location.

For example, if you are 10 yards behind the yard marker, you have yards to the middle of the green. Subtract 10 percent to account for high altitude, says "Golf Digest. Choose the club you would normally hit from yards away.

Consider the temperature and humidity, notes Langer. The ball won't travel as far in cool weather or humid weather.

It will travel farther in warm weather and when the air is dry.

Take into account your ball flight, says Fred Funk. If you hit shots with a high trajectory, they will fly farther in high altitudes. If you hit low shots, you won't get as much additional distance as those who hit the ball high. One such golfer, Kenny Perry, subtracts 20 percent to calculate his yardage in altitudes above 3, feet.

If he has yards to the pin, he selects a club he normally hits yards at sea level. Prepare to be wrong and try not to get frustrated if your calculations don't work out well. Although the general rule is to deduct 10 percent to determine the "true" distance for shots to the green at high altitude, it's not a rule you can bank on.

As "Golf Digest" put it, the 10 percent rule, even for the professionals, is "more of a ballpark figure than an exact science. Jim Thomas has been a freelance writer since He wrote a book about professional golfers and has written magazine articles about sports, politics, legal issues, travel and business for national and Northwest publications.

Doesn't it seem like you hit your wedge much higher? It's all perception. In fact, you hit each club in your bag with a full swing about the same maximum height. Why is this? And why does it appear that you hit your short irons so much higher than your longer clubs?

Observe how the maximum height for each club is about the same. It all has to do with what you are observing. What's very different between your Driver and full wedge is the launch angle. The full wedge trajectory has a much greater launch angle. Therefore, the ball climbs to its maximum height in a much short distance.

The Driver trajectory climbs gradually. Once the ball is at its peak, it's a long ways away, and therefore it appears to be low. It's much like a distant mountain. It appears to not be very high because it is a long ways away and low on the horizon. But, from experience, your know it is high. Likewise other objects at a distance such as trees and buildings appear very low on the horizon, but you know there are actually high.

A golf ball launched by a short iron like a wedge climbs very quickly, thus it is very high relative to the horizon.

You need to be looking more upwards, at a greater angle, to follow its flight than the flight of the Driver. The angle at which you need to look up is greater. Look at the trajectory graph below. The various values such as maximum height, carry distance, launch angle, etc are consistent with the Trackman data above. Take a look at the trajectory graph below of just the 5-iron and 9-iron trajectories. The trajectory that carries yards is an average 5-iron trajectory for a PGA Tour player.

I've marked on each trajectory the angle above the horizon as seen by the golfer during each second of flight. So, after 1 second, the 9-iron is higher but has travelled less distance because the ball is not moving as fast as when struck with a 5-iron.One of the many things that set tour pros apart from amateurs — even very good ones — is the ability to control the ball's trajectory.

This is an important factor in windy conditions, but also when playing to different pin placements, carrying distant hazards or hitting a shot that runs after landing. There's no real magic to altering the height of your shots. It's largely done by changing the ball's position in your stance, which determines the club's effective loft at impact.

golf trajectory formula

As a simple rule, the farther up in your stance you play the ball — toward the left foot, for a right-hander — the higher it will fly. Play it farther back, or to the right, to produce a lower flight. It's important to keep the hands ahead of the ball and the shaft leaning toward the target on iron shots. The farther back you play the ballthe more the shaft will lean.

The same concept applies on chips and bunker shots. Control Trajectory by Varying Ball Position. The ability to control the trajectory of your shots might seem like a skill that is a bit out of reach. After all, as an amateur golfer, you don't have the control over your ball which is demonstrated by the top pros. However, even if you have a lot of work to do on your game, it is still worth your time to learn how to alter your trajectory on command.

Not only will you add some new shots to your game as you learn this skill, but you will also improve the overall quality of your swing in the process. One of the best ways to control the trajectory of your shots is by varying the ball position you use at address. When you set up over the ball, you have to determine where you are going to stand in relation to the position of the ball on the ground.

Are you going to line up with the ball in the middle of your stance, or up toward your front foot? Or, are you going to play the ball back in your stance, closer to your right foot for a right-handed golfer?

Choosing your ball position is one of many decisions that needs to be made before you can go ahead with a swing. This is an important decision, of course, as it is going to largely determine the type of trajectory you use for the shot. Many amateur golfers make the mistake of trying to make dramatic swing changes when they want to produce a different-than-usual ball flight.

Generally speaking, that is just not necessary. Instead of changing your swing in any significant way, try adjusting the location of the ball within your stance.Golf Ball Trajectory Model After many years of research and testing, we have developed a mathematical model for the flight of a golf ball. We use this model to predict the flight based on initial golf ball parameters such as speed, launch angle, spin along with environmental conditions such as air temperature, air pressure, humidity, etc.

The model also predicts those initial conditions from the collision with a golf club swinging at various club head speeds.

Trackman has been publishing some of its empirical results in its newsletters. My model assumed a temperature of 25 degrees Celcius 77 Fno wind, near sea level. The Trackman data is accompanied by the note, " Please be aware that the location and weather conditions haven't been taken into consideration.

Besides these reservations the data is based on a large number. Thus, the Trackman data would have been collected at various temperatures, altitudes and wind conditions.

Some shots would have been with the wind, some into the wind, some in a crosswind. Note, that if air temperature is higher and altitude is higher, the ball will carry farther.

As can been seen from the data, the Tannar Model predicts quite closely the golf ball parameters measured by the Trackman for the two club speeds of mph and 94 mph.

December 13, - LiveScience. The video features an extensive simulation based on research conducted by scientists at Arizona State University and the University of Maryland looking at the effects of air drag on the dimples on a golf ball. Click on the graphic below. Williams 11 provided data on the carry and drive of a British golf ball hit with a driving machine.

He did not cite the loft of the driver used but it has been assumed that it was a standard 10 o commonly used at the time. I varied the ball speed in my model without sidespin or wind. My model replicated the linearity of the dependency with a similar equation. Besides these reservations the data is based on a large number of shots and give a good indication on key numbers for tour players.

Comparison figures are recorded in the table below. Since there was no recording of loft angle, launch angle, and atmospheric conditions, the reasons for the differences can only be speculated. It is difficult to find empirical data that has well documented conditions of launch.

My model does predict, however, a linear dependency between launch speed and carry as determined by McPhee and Andrews 8MacDonald and Hanzely 7 as well as most recently A. Penner Using my model, I compared its predicted results to the results of McPhee and Andrews because they investigated the effects of sidespin see Appendix B.Or do you struggle to get it up in the air, sometimes coming up short for lack of carry?

The variables that determine trajectory are easy to understand, yet controlling ball flight is one of the most difficult skills to master.

Outside the professional ranks, few golfers are able to do it consistently. Trajectory, of course, is a function of clubface loft. If your hands are ahead of the ball at impact and the shaft leaning toward the target, the loft is decreased — perhaps significantly.

The result is a lower shot than the loft alone indicates. Search Golf-Info-Guide. When it comes down to it, everything you do within your swing is all about ball flight. All of the technical adjustments you make, and all of the mechanics you try to pay attention to all boil down to the flight that you are able to achieve once the ball leaves the club face.

Obviously, there is nothing you can do about the flight of the ball once it takes off — so all of your effort has to go into making your swing and reliable and repeatable as possible.

The best golfers are the ones who have a variety of different golf ball flight paths at their disposal. With practice, you can probably get pretty good at hitting the same one trajectory over and over again.

How to Calculate Slope Rating

While this is a good start to playing quality golf, it will take more than that to really lower your scores. After all, golf courses come in different shapes and sizes, so it requires different trajectories to be able to handle them successfully.

There is no one single ideal golf ball trajectory — instead, the ideal golf ball trajectory is the one that works best for the shot that is in front of you. Assuming you already play golf, you probably have one or two ball flights that you are pretty comfortable with. Maybe you have picked them intentionally, or maybe they are just what happens when you swing the club naturally.

Either way, in order to step up your game you are going to want to go further and actually understand the physics of a golf ball flight. Once the physics of a golf ball flight are no longer a mystery, you can begin to dissect your swing and make the changes necessary to hit the kind of shots that you need out on the course. Any level of golfer can work on fixing ball flight problems in their game and learning new shots to be better prepared for their next round.

Whether you are fighting a golf ball trajectory too high, or a golf ball trajectory too low, the answer is certainly found within your swing technique itself. First we are going to cover some of the basics of golf ball flight and why the ball behaves the way it does in the air. Following that, we will analyze some of the common ball flights that most golfers wish to achieve, and the swing characteristics necessary to make them happen.

All of the instruction included below is based on a right handed golfer, so please be sure to reverse it if you are a left handed golfer. What Makes the Golf Ball Move? If the ball went exactly where you were aiming every time you made a swing, golf would actually be pretty boring. The unpredictability of the game, and the never ending pursuit of improvement, is what keeps us coming back. The spin that you impart on the ball has everything to do with how it is going to fly, and what direction it will end up traveling.

While the position of the club face largely determines the initial direction of the shot, the spin quickly takes over and controls the flight the rest of the way. If you are a golfer who struggles with a slice, that frustrating ball flight is certainly the result of unintended spin. When you put left to right spin on the golf, that is the direction it is going to move in the air.

Controlling not only the kind of spin you put on the ball, but also how much, is the real secret of managing your ball flights.The total distance achieved by a golf club is based on several factors: the loft achieved, the carry distance achieved Note: The carry distance is the yardage from the point of impact to the point of landing.

Drivers are designed to maximize the ball's carry distance, so a driver's loft angle ranges from 8 to 13 degrees, depending on the specific brand or model of driver. Woodsranging from a 2-wood to a 5-wood are also used for distance, but their loft angle is slightly greater than a driver.

This angle provides the golfer with distance, with a little more loft than a driver. Ironsranging from a 1-iron to a 9-iron are used for distance with the larger numbered irons being used for their ability to get loft for a ball. Wedgesfor pitching, sand or lobbing, are primarily used for their ability to get under a golf ball and give it maximum loft.

Go to the driving range and hit ten golf balls with each club. Keep track of the ten distances you achieve with each club.

Repeat the charting monthly, or more frequently if you are actively working on your swing. The distance achieved by a specific golf club will vary from player to player and from day to day based on the conditions. Tour distance information was compiled from stats on golfwrx. Jack H. Menu Menu Log In. By Teresa Justine Kelly. Sign up for free and create yours now! Key Factors to Achieve Golf Club Distance The total distance achieved by a golf club is based on several factors: the loft achieved, the carry distance achieved Note: The carry distance is the yardage from the point of impact to the point of landing.

The more angle on the club face, the greater the potential loft of the club. For example, a driver is designed for distance, so the club face is almost straight up and down. This causes only an degree loft. In comparison, a pitching wedge is designed for loft, so the club face is more parallel to the ground, with a degree loft. Distance : According to Golfmentor. Men tend to have faster swing speeds which causes them to hit the ball farther.

However, many women are long hitters, with some LPGA pros hitting the ball as far, or farther, than men on the course.
