Discover the hidden meaning behind the term COR
While many golfers have heard the term COR before, few understand its true meaning and importance. At its core, COR is a measure of the efficiency of energy transfer between the clubface and the ball. But what does this really mean for your game? Let’s take a closer look.
At its most basic level, COR determines how much energy is lost or gained when the ball hits the clubface. A higher COR means more energy is transferred to the ball, resulting in longer drives and better overall performance. But there’s more to it than just raw power. COR also affects spin rates, launch angles, and other important factors that can make or break a shot.
How is COR tested and measured?
Testing the COR of a clubface involves using a device called a “smash factor” machine, which measures the ball speed before and after impact. The COR is then calculated by dividing the post-impact ball speed by the pre-impact clubhead speed. While this may sound simple, there are a lot of variables at play, including the type of ball being used, the temperature and humidity, and even the altitude of the course.
Why do professional golfers swear by COR?
Professional golfers know that COR can mean the difference between a winning shot and a missed opportunity. With millions of dollars on the line, every advantage counts. That’s why many pros invest in custom clubs with high COR ratings, tailored to their unique swing styles and preferences.
- But it’s not just the pros who can benefit from COR technology. Even amateur golfers can improve their game with the right equipment.
- By choosing clubs with high COR ratings, you can add distance and accuracy to your shots, helping you to score lower and have more fun on the course.
The future of COR in golf

Whether you’re a seasoned pro or just starting out, understanding the meaning and importance of COR is essential for improving your game and taking your skills to the next level. So why not invest in the latest COR technology and see how it can transform your golfing experience?
Unveil the science behind COR and its impact on your game
Are you a golfer looking to improve your game? Then you must have heard about COR or Coefficient of Restitution, which is a term that refers to the measurement of energy transferred during a collision between a clubface and a golf ball. But what exactly is COR, and how does it affect your game? Let’s delve deeper to understand the science behind it.
COR is the ratio of the initial and final velocities of two objects after a collision. In golf, it measures the energy transferred from the clubhead to the ball during impact. The United States Golf Association (USGA) regulates the COR of clubheads to ensure that they do not exceed the legal limit of 0.8A higher COR means that the ball will travel farther, making it a desirable feature for golfers.
Understanding the impact of COR on your game
Now that you know what COR is let’s discuss its impact on your game. A higher COR means that the ball will travel farther with the same amount of force applied. This is because more energy is transferred from the clubface to the ball, resulting in a greater ball speed. This can be beneficial for golfers who struggle to achieve maximum distance off the tee or fairway. However, a higher COR also means that the ball will be less controllable, making it difficult to control the direction and spin of the ball.
Factors affecting COR
- Clubhead Speed: The speed of the clubhead affects the COR. A higher clubhead speed results in a higher COR as more energy is transferred from the clubface to the ball.
- Temperature: The temperature affects the COR of the ball. A warmer ball has a higher COR as it is more elastic.
- Ball Type: The type of ball used affects the COR. Different balls have different CORs, and choosing the right ball for your game is essential for optimal performance.
Choosing the right club for your game
Now that you know the science behind COR and its impact on your game, it’s essential to choose the right club for your game. While a higher COR can provide more distance, it’s important to consider other factors such as control and spin. It’s recommended to get fitted by a professional to ensure that you are using the right club for your game and swing.
Understanding the science behind COR and its impact on your game can help you make informed decisions when it comes to club selection. Keep these factors in mind to improve your game and achieve optimal performance on the course.
How COR is tested and measured in golf clubs
If you’ve been following the latest developments in golf club technology, you’ve probably heard of COR. But what exactly is COR, and how is it tested and measured in golf clubs?
Simply put, COR stands for Coefficient of Restitution, which measures the efficiency of energy transfer from the clubface to the golf ball. The higher the COR, the greater the ball speed and distance that can be achieved with a given amount of swing speed.
Measuring COR
To measure COR, golf club manufacturers use a machine called a “smash factor” robot. The robot strikes the center of the clubface with a golf ball at a predetermined speed, and then measures the velocity of the ball as it leaves the clubface. This velocity is then compared to the initial speed of the ball to determine the coefficient of restitution.
Another method used to measure COR is the “pendulum test.” In this test, the clubface is held stationary while a small weight is dropped onto it. The rebound of the weight is measured, and the ratio of the rebound height to the initial drop height is used to calculate the COR.
The USGA and COR Limits
The United States Golf Association (USGA) sets limits on the maximum COR allowed in golf clubs for official play. These limits vary depending on the type of club and the level of play. For example, the maximum COR for drivers is currently set at 0.830 for professionals, while it is set at 0.860 for amateur players.
- Testing and measuring COR is essential to ensuring that golf clubs meet the standards set by the USGA.
- The smash factor robot and pendulum test are two commonly used methods for measuring COR.
- The USGA sets limits on the maximum COR allowed in golf clubs for official play, which vary depending on the type of club and level of play.
Why COR matters more than you think in golf
If you are serious about your golf game, then you should know what COR is and why it is so important. COR, or coefficient of restitution, is a measure of how much energy is transferred when a clubface strikes a ball. In other words, how much energy the clubface retains after the impact with the ball.
One reason why COR matters so much in golf is because it affects the distance you can hit the ball. A higher COR means that the ball will travel farther and faster. This is why golf club manufacturers spend so much time and effort trying to maximize the COR of their clubs.
What is COR?
COR is a measure of how efficiently energy is transferred from the clubface to the ball during impact. The higher the COR, the more energy is transferred, resulting in longer shots. The USGA sets a limit of 0.83 for COR, which means that no club can have a COR higher than this.
How is COR measured?
- Pendulum test: A heavy weight is suspended from a pivot point and swung towards the clubface. The clubface strikes the weight, and the resulting rebound speed is measured.
- Ball test: A ball is fired at a clubface at a specific speed, and the resulting ball speed is measured. The difference between the initial ball speed and the final ball speed is used to calculate the COR.
Why does COR matter?
COR is a critical factor in determining how far you can hit the ball with your golf clubs. If you are looking to maximize your distance and improve your golf game, then you need to pay attention to the COR of your clubs. A higher COR means that you will be able to hit the ball farther and with less effort, which can lead to lower scores and greater enjoyment on the course.
The Real Reason Why Professional Golfers Swear by COR
Golf is a sport that demands precision and accuracy, and it’s no surprise that professional golfers are always looking for ways to gain an edge over their competition. One of the most important factors in achieving success on the course is the coefficient of restitution (COR) of their golf clubs.

How COR affects your shots and your scorecard
If you’re a golfer, you know that every shot counts. That’s why it’s important to understand how the Coefficient of Restitution (COR) of your golf clubs can affect your shots and ultimately, your scorecard. COR is a measure of how much energy is transferred from the clubface to the ball at impact. In simpler terms, it’s a measure of how “springy” your clubface is.
When a clubface has a high COR, it means that it will compress more on impact and then quickly rebound, propelling the ball forward with more speed and distance. This means that a clubface with a high COR will help you hit the ball farther, even on mishits. On the other hand, a clubface with a low COR will not compress as much, resulting in less distance and a weaker shot.
Accuracy and Forgiveness
While distance is important, accuracy and forgiveness are also crucial to a good scorecard. A clubface with a high COR can actually make it harder to control your shots, especially if you have a tendency to mishit. Shots hit with a high COR clubface tend to go farther off-line if you don’t hit the sweet spot, while a clubface with a lower COR can be more forgiving and help keep your shots on-target.
The Importance of Clubfitting
Now that you understand the basics of COR, it’s important to note that not all golfers will benefit from the same level of COR in their clubs. Golfers with slower swing speeds will typically benefit more from a higher COR, as it can help them generate more ball speed and distance. Golfers with faster swing speeds may benefit more from a lower COR, as it can help them better control their shots and keep them on-target.
That’s why it’s important to get properly fitted for your golf clubs by a professional. They can help you determine the right level of COR for your swing speed and playing style, as well as other important factors like shaft length, flex, and weight.
The Bottom Line
So, what’s the bottom line? COR is an important factor to consider when choosing your golf clubs, but it’s not the only factor. While a high COR can help you hit the ball farther, it can also make it harder to control your shots. It’s important to find the right balance of COR, accuracy, and forgiveness for your individual game. And, of course, proper clubfitting can make all the difference in your performance on the course.
The surprising history of COR in golf – you won’t believe it!
When we think of golf technology, our minds often go to modern innovations such as adjustable drivers, launch monitors, and high-tech golf balls. However, one of the most significant advances in golf equipment technology actually has its roots in the 19th century.
The concept of Coefficient of Restitution (COR) can be traced back to the development of the gutta-percha ball, which replaced the featherie ball in the mid-1800s. The gutta-percha ball was made from the rubber-like sap of the gutta-percha tree, and it was much more durable and affordable than the featherie ball. However, it had a major flaw – it didn’t fly as far as the featherie ball.
The early days of COR
To address this issue, golf ball manufacturers began experimenting with different materials and designs to increase the distance that a ball could travel. In 1882, an American inventor named Coburn Haskell developed the first ball with a solid rubber core. This new design was a significant improvement over the gutta-percha ball, but it still had limitations.
The breakthrough came in 1905, when a British physicist named Frederick Guthrie discovered the concept of COR. He found that when two objects collide, the speed of the resulting rebound is related to the amount of energy that is retained in the collision. In golf, this meant that a ball with a higher COR would rebound more efficiently off the clubface, resulting in greater distance.
The evolution of COR in golf
- As golf ball technology continued to improve, so did the understanding of COR. In the 1960s, the USGA (United States Golf Association) introduced regulations limiting the COR of golf balls to 0.83, in an effort to prevent manufacturers from creating “superballs” that would travel too far.
- In the 1990s, golf club manufacturers began incorporating the concept of COR into their designs. Drivers with “hot faces” that produced high COR ratings became popular among professionals and amateurs alike.
The future of COR in golf
Today, COR remains an important factor in golf equipment design. Manufacturers continue to push the limits of what is allowed by the USGA, and advancements in materials science and engineering are allowing for even greater efficiency in ball rebound. As the sport of golf continues to evolve, it’s likely that we will see even more exciting developments in the world of COR.
