What is CG in golf iron?
CG stands for centre of gravity and in a golf club head it is the point that all of the weight is acting through. If you drew a line through all the different vertical and horizontal balance points of the club then the intersection of all those lines is the centre of gravity.
What does CG position mean?
CG stands for centre of gravity and in golf it is used in terms of equipment. When manufacturers use the term you often hear phrases like, 'the centre of gravity is low, the centre of gravity is as far back as possible, or the centre of gravity is high.
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 causes toe shots?
The most common cause of hitting off the toe is releasing the club early, the wrists unhinging and the right arm straightening too soon on the downswing. Players who do that hit a lot of fat shots, so they learn to yank the club upward either by standing up or bending their left elbow.
What is bulge and roll?
What is bulge and roll? Bulge is the curvature of the clubface from the heel to the toe. Roll is the curvature of the face from the crown of the club to the sole. Both features have a huge influence on ball flight, due to the science behind gear effect.
What is gear effect on wood clubs?
Gear effect is the term used to explain how and why hitting the ball off-centre changes the ball flight. When the ball makes contact with the heel and toe it will cause the club face to change the direction it was pointing and will affect the spin, the ball will turn towards the Centre of Gravity.
What happens if CG is too far forward?
In extreme cases, a CG location that is beyond the forward limit may result in nose heaviness, making it difficult or impossible to flare for landing. Manufacturers purposely place the forward CG limit as far rearward as possible to aid pilots in avoiding damage when landing.
Where is the center of lift?
The location along the chord of an airfoil at which all lift forces produced by the airfoil are considered concentrated. This is generally near the quarter-chord point.
How do you tell if CG is forward or aft?
Your airplane balances on its CG, and that location is where the downward force acts on your aircraft. Your lift acts upward from your wing, at a point called the center of lift. And the center of lift, as long as you are within the aircraft's CG limits, is always aft of your CG.
Where is the center of gravity in a coat hanger?
Balance the hanger from a corner with the string. Again, allow the mass to hang down and trace a line along the string. Now balance the other corner while holding the string and repeat the tracing. The point where all three lines intersect is the center of mass for the hanger.
How can you check that you have correctly found Your Shape's centre of gravity?
When students hang the shape from several different points they see that the plumb line always passes through the same spot. You have correctly marked the shape's centre of gravity if: when you pin your shape through its centre of gravity it is stable and balanced.
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 ...
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.
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.
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.
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.
CG Meaning – Center of Gravity In Golf Explained

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.
What is the position of the CG in the head?
The taller the clubhead and/or the more weight that is placed on the upper portions of the head, the higher the position of the CG will be in the head. The more shallow the clubhead and/or the more weight that is placed on the bottom or sole of the head, the lower the position of the center of gravity will be.

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.
How does CG affect golf?
On a comparative basis: 1 Drivers with forward CG locations often feel heavier than those with rear CG placements 2 A forward CG location will cause the shaft to feel stiffer. 3 Because of the effect on closure rate, forward CG drivers may be harder to square, and some golfers will find it difficult to control the club during swing
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 ...
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 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.
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 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 are forward CG drivers harder to square?
A forward CG location will cause the shaft to feel stiffer. Because of the effect on closure rate , forward CG drivers may be harder to square, and some golfers will find it difficult to control the club during swing. While it may not be universally true, I ...
What is a CG in golf?
A golf club head CG is one small point no bigger than the sharp end of a pin. Furthermore, this point represents an intersection of all possible balance points. All club head designs have varying CG positions. This fact is true for both woods and irons. Similarly, wedges and putters also have a specific CG.
What is the center of gravity of a golf club?
It determines the performance of golf clubs in terms of ball flight launch and trajectory. The center of gravity is different in most club designs. By different, we mean in a slightly different location within the club head,
How is the center of gravity of a golf club controlled?
The center of gravity position in the club head is initially controlled by the height, width and depth of the club head. Whereby it is influenced by how much of the head’s weight is placed in different areas of the club head.
What does depth CG mean?
Depth CG location = how far back from the club face it is located.
Where is the center of gravity?
The center of gravity is a single point inside the club head. Therefore, its location needs to be defined in 3-dimensions.
