What does center of gravity mean in golf?
Brent Kelley is an award-winning sports journalist and golf expert with over 30 years in print and online journalism. "Center of gravity" (abbreviated CG) is term golfers often encounter in articles about golf equipment, advertisements of golf clubs, and on the websites of golf club manufacturers.
How does loft affect center of gravity on a golf club?
As the loft increases, the center of gravity moves higher because the golf ball will more frequently be struck higher up on the face, particularly as a chip or pitch shot is hit from rough and slides up the face at impact. How is the center of gravity determined in a golf club, and how can you change it?
What does low CG mean on a golf club?
CG Low (toward the bottom of the club head) will cause the ball to launch higher and spin less. When it comes to drivers, a low CG design has proven effective for almost all golfers, and most modern driver companies in 2020 have very low CG designs.
What is draw-bias center of gravity in golf clubs?
Several manufacturers make drivers with a draw-bias center of gravity, meaning the center of gravity is moved toward the hosel of the club so it's easier to promote a closed -- or at least more square -- clubface at impact. On irons, most golfers again want a low and back center of gravity to help them get the ball in the air and flying farther.
How is Centre of gravity used in golf?
The center of gravity on a golf club refers to the place where all the points of balance on a golf club intersect. It's a really important feature of a golf club, as the center of gravity -- often just called CG -- helps determine how easy it is to create ideal launch conditions for a golf shot.
Where is the center of gravity in a golf swing?
While CG is mostly found near the middle of an object, it is generally found closer to the face of a golf club due to the face being the thickest and heaviest part of the club. The hosel is also a heavy part of the golf club and this too is located closer to the face.
What effect does gravity have on 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.
Does a golf ball have a center of gravity?
Did you know that there is a center of gravity in a golf ball? Well actually there is a center of gravity to almost everything, but rarely do we think about a golf balls COG. Most of the terminology we here today is about drivers.
What is Moi and CG in golf?
Moment of Inertia (MOI) and Center of Gravity (CG) In golf, "forgiveness" refers to the engineering and/or the design elements in golf clubs that lessen the effects of bad swings and poor contact with the ball.
What is the center of gravity?
Your centre of gravity is the point where the mass of the body is concentrated. The centre of gravity (COG) of the human body is a hypothetical point around which the force of gravity appears to act. It is point at which the combined mass of the body appears to be concentrated.
Do harder golf balls go further?
The harder the ball, the further it tends to go with less spin. Harder golf balls tend to be much cheaper than softer golf balls. If you lose balls regularly then harder golf balls could be ideal for you. Soft balls stick to the grooves of your irons and wedges and spin much more.
How many G does a golf ball experience?
In fact, during certain stages of impact, the ball experiences more than 50,000-g's of acceleration! An oversized driver can increase distance up to 2% for a 1″ OFF CENTER hit when compared to that of a normal-sized driver. The benefit of having an oversized driver is only for OFF CENTER hits.
Does gravity stop a ball from rolling?
So, the gravitational force will not do any work on the ball, and it won't keep moving. If you take into account objects other than the earth, these will have a minuscule effect; nowhere near the earth's. The friction will negate these many times over - so no, gravitational forces will not make the ball keep rolling.

Do golf balls need balancing?
If you think that the inconsistencies of the greens you putt on will counteract any effects an unbalanced golf ball may have, then the answer is No. A golf ball is unbalanced when its centre of gravity is not perfectly in the middle.
What Is A Golf Clubs Center Of Gravity And Why Should I Care?
Anyone who has ever had a club with moveable or adjustable weights has had the ability to move the CoG of their driver.
Why Is The Center Of Gravity Of A Club Important?
You hear it a lot, “lower center of gravity (CoG) for more distance” but what does this really mean? It is a phrase that really became part of mainstream golf talk in around 2014 after some major breakthroughs from the big manufacturers in terms of moving the CoG and performance.
What Is Center Of Gravity?
In simple terms, the CoG of anything is the point at which the weight of an object is perfectly balanced.
How Does It Effect The Performance Of The Club?
This may be the most important factor behind the performance of a club.
Should I Be Using High Or Low CoG? How Do I Know?
The easy way to remember it is that higher handicap players and slower swing speed players will tend to do better with high CoG.
What Is MOI In A Golf Club And Why Does It Matter?
MOI stands for ‘ moment of inertia’ and refers to how much a club resists twisting on impact with the ball. The higher the MOI, the more forgiving a club is.
Does CoG affect putting?
Yes, it does. Many studies have been done on this and the consensus is that moving the CoG closer to the face of the putter can improve launch conditions and even aid the stroke.
What does center of gravity do for a golfer, and where is it located?
On a driver, most golfers will benefit from a center of gravity that's low and back, meaning it's situated closer to the sole and back of the crown of the driver. With this CG position, a golfer is able to hit the ball higher with more backspin, meaning it'll be more controlled and more likely to stay in play.
Why does the center of gravity move higher?
As the loft increases, the center of gravity moves higher because the golf ball will more frequently be struck higher up on the face, particularly as a chip or pitch shot is hit from rough and slides up the face at impact.
What is the draw bias of a golf driver?
If you're a golfer struggling with keeping the ball from slicing, moving hard to the right, with your driver, then you may want a driver with a center of gravity that promotes more of a draw. Several manufacturers make drivers with a draw-bias center of gravity, meaning the center of gravity is moved toward the hosel of the club so it's easier to promote a closed -- or at least more square -- clubface at impact.
What is CG position in golf?
With this CG position, a golfer is able to hit the ball higher with more backspin, meaning it'll be more controlled and more likely to stay in play. However, some better golfers want a more forward center of gravity while keeping it low, so as to keep that point near where impact happens and lowering spin. That creates some more distance and ...
How to change center of gravity?
Changing the center of gravity position, then, is a function of moving weight where you want the center of gravity to be. That can be done in many modern drivers by shifting weights on the sole. It's possible with some fairway woods and hybrids.
How is the center of gravity determined?
The center of gravity is entirely determined by the mass properties of a club. In other words, where the weight is concentrated in a golf club determines the center of gravity position. The more weight placed low and back in a club, the lower and further back the center of gravity will be.
Can you move the center of gravity on irons?
Generally speaking, you can't move the center of gravity on irons and wedges.
Where is the center of gravity on a golf club?
As you might expect given its label, the center of gravity is always located very near the center of the clubhead. The CG of every driver measured for this series of articles is located within a box that’s 14mm front to back and 12mm top to bottom.
What is the center of gravity?
Center of Gravity (CG or CoG) is the point at which all of the weight of an object appears to be concentrated. An object can be balanced on a small flat point placed directly beneath its center of gravity.
What is a club closure rate?
Closure Rate or Dynamic Closure Rate is the rate at which the clubhead closes during the downswing. The more forward the CG the slower the closure rate. Clubs with slower closure rates are generally described as being more workable. Back CG designs with faster closure rates are more forgiving, and can help to mitigate a slice.
What is dynamic loft?
Dynamic Loft is the actual loft delivered to the ball at impact.
Why does the driver head have a slight forward bias?
Now that said, the CG location of a driver head has a slight forward bias because: The face is much thicker and heavier than the rest of the body. The hosel (and all of its weight) is near the front of the club. 2.
What are the three things that affect CG movement?
The significance and impact of flipping, sliding, or any other type of CG movement depends on three things: 1. The direction the weight is being moved. 2. How much weight is being moved. 3. How far the weight is being moved. The more weight you can move over a greater distance, the more the CG will shift.
Why does CG location matter?
CG location matters because it heavily influences both performance and feel. How high your driver launches, how low it spins, how it feels, and how it sounds at impact, that all begins with its center of gravity. Before we dig deeper into the specifics of how CG location impacts both performance and feel, there are a few things we need ...
Why is CG important in golf?
While CG may seem like marketing speak based on how frequently golf club companies mention the term, CG is actually incredibly important when it comes to performance and feel. Where CG is located on a golf club influences launch, spin, feel, sound, forgiveness, how a shaft performs in conjunction with the club head, and so much more.
What degrees are lower lofted wedges?
That’s because lower-lofted wedges (46-54 degrees) are played more often on full shots where higher launch is beneficial, and higher-lofted wedges (56-60 degrees) are used on shots where lower launch and higher spin is important for control. CG is also closely related to MOI (moment of inertia), which we’ll cover in-depth on the next installment ...
What is the CG location of an iron?
CG location for irons can vary drastically depending on the intended consumer, which ranges from Tour players to game-improvement golfers. In the most general sense possible, golfers require low CG for long irons in order to launch them high, and progressively higher CGs in their short irons to launch them low with more spin and control. Game-improvement irons typically have lower and more rearward CGs throughout an iron set, while players irons have higher and more forward CG locations for greater workability.
Why is it important to consult a golf fitter?
It’s incredibly important to consult with an expert fitter to help determine what golf clubs match your game and preferences. The sheer amount of options on the market can be overwhelming for anyone.
What does CG stand for in golf clubs?
When it comes to golf club technology, the term “center of gravity” — “CG” or “CoG” for short — gets thrown around quite a bit, but it isn’t often explained to the average golf consumer.
What is CG forward?
Here are some basic rules of CG as they relate to golf clubs and performance at impact: CG Forward (toward the face) will lower launch and spin, and generally make the club play a bit less forgiving. CG Back (away from the face) will increase launch and spin, and generally make the club play more forgiving. CG High (toward the top of the club head) ...
Where is the CG on a golf club?
The CG of a golf club head is typically very close to the center of the head, as you’d expect, but the exact CG location is extremely important. Any minute changes in CG can have a drastic effect on performance.
CG Meaning – Center of Gravity In Golf Explained
CG or center of gravity is a very common acronym that is used by golf brands. For example, the low CG of irons more geared towards beginners. The center of gravity is low, deep (meaning pushed farther back), etc. So what does all this really mean?
How Golf Club CG Affects Shots and Performance?
Low CG, meaning towards the clubhead bottom, results in a higher launch with less spin.
Center of Gravity In Golf Clubs Also Affects Feel!
The courtesy of CG extends to not just trajectory and spin but also feel.
The Takeaway!
In summary, the role of CG in golf clubs is no light matter. More advanced technologies are coming up in order to further improve the location of the center of gravity. For example, now there are clubs with even lower CG placement to increase launch and minimize spin further just to boost distance more drastically.
Why is it important to hit the ball in direct line with the center of gravity?
Why is this important? Because, in order for you to hit your driver with its most perfect potential, you must hit the ball in direct line with it’s center of gravity point. NOT THE SO CALLED SWEET SPOT. How large is it? About the size of a pinhead.
How does the COG affect the loft of a golf club?
The COG affects the "true loft" of the club, where you get the maximum ball speed with minimal twisting and where you impart the most spin on the ball off the driver. By hitting just 1/2" below the COG vs. 1/2" above, the difference in spin rate can be well over 1,000 rpm's.
What is the sweet spot on a golf club?
Okay, sometimes the CG is referred to as the “sweet spot” of the wood head-or rather the sweet spot is the position where the CG would PROJECT from inside the head onto the FACE. When impact results in the ball contacting this projected point of the CG on the face with the head traveling parallel to the ground, the head will not rotate in any direction vertically or horizontally about its CG, and the maximum transfer of energy from the club head will occur.
What is the CG in math?
The technical definition, of the CG is referenced as a dimension on each of the three axes of 3-dimensions. The X-axis location of the CG represents how far the Cg is from the centerline of the hostel bore. The Y-axis location of the Cg tells us how high the Cg is straight up from the lowest point of the sole, and the Z-axis position is how far back the Cg is from either the center of the hostel bore or the face. Simple EH? Just study the above images and it is quite clear.
Is the center of gravity on a golf club the center of gravity?
On most golf clubs, the center of gravity will not be the exact center of the club face. It should be slightly inside of center. CONCLUSION It is most important to be aware of where the spot on your driver’s face gives you the ultimate performance. There is much more to fitting a golfer with the correct center of gravity in regards to the effect ...
