What is moi on a golf ball?
The acronym "MOI" stands for "moment of inertia," and in golf MOI is a measurement of a club's resistance to twisting. The term is usually applied to clubheads, but can also be applied to golf balls and even shafts.
What is Momoi in golf clubs?
MOI is an acronym that stands for “moment of inertia.” This measurement (grams per centimeter squared) shows how much resistance a clubhead has to twisting.
What does Moi mean on a driver?
High MOI means more fairways hit with the cost of distance. Low MOI means more distance but reduced control of the ball on off-centre hits. If you are playing a low MOI driver your off-centre hits will become wilder shot shapes and misses.
Are high moi golf clubs right for You?
High MOI isn’t always ideal for ALL golfers, however. Highly skilled players, such as PGA Tour pros, often opt for clubs-especially irons-with a bit less MOI, or forgiveness. That’s because less twisting of the face actually reduces the ability to hit draws and fades on purpose.
Which golf driver has the highest MOI?
G425 MaxThe G425 Max has the highest MOI (a measurement of forgiveness) on the market, and its 460 cc head features a 26-gram moveable tungsten weight in the rear to help golfers dial in ball flight bias.
What does high MOI mean in golf clubs?
A high MOI means that the club is more stable and therefore more resistant to twisting, which translates to more ball speed and a straighter shot. So for the average golfer a high MOI is beneficial as it will lead to consistently straighter and longer shots from off centre strikes.

What loft driver should I use?
Choose a loft to try based on your assessed club-head speed. If it is between 95 and 104 mph, a 10- or 11-degree loft will be appropriate. If it is between 105 and 115 mph, a loft between 7 and 9 degrees should be considered. Golfers with club-head speeds below 85 mph should use a loft angle between 14 and 20 degrees.
Are steel shafts better than graphite?
Typically, steel shafts are much heavier, more durable and are generally less expensive than their graphite counterparts. They are more often than not made from stainless steel and they tend to weigh in between around 90g-120g. Torque or lateral twisting found in all graphite shafts is lower in steel irons.
What is MOI matching?
MOI Matching is simply a replacement for swingweight matching in the fitting process. Clubmakers will fit golfers for every one of the other key fitting specifications based on the same fitting procedures that they have developed and with which they are experienced.
What does Moi mean on a driver?
moment of inertiaAn acronym, MOI stands for “moment of inertia.” MOI is measured in grams per centimeter squared and shows how much resistance a clubhead has to twisting. The more resistance it has, the higher the MOI reading and, importantly for golfers, the more forgiving the club will play.
What does MOI 10 mean?
Multiplicity of infection (MOI) is a frequently used term in virology which refers to the number of virions that are added per cell during infection. If one million virions are added to one million cells, the MOI is one. If ten million virions are added, the MOI is ten.
What does an MOI of 2 mean?
An MOI of 1 is equal number of cells and virus particles. So in your case you would use 2ul of virus for 10,000 cells. An MOI of 2 would be twice the number of virus particles compared to cells.

Why do golfers have high MOI?
This is because they want to retain the ability to work the ball left and right. A higher handicap golfer will be more likely to be trying to hit the ball straight and is more likely to miss the centre of the club face – so they will benefit from high MOI in an iron.
What does high MOI mean?
They are effectively the same thing. High MOI means high forgiveness and stability. Many club designers have told me that it’s mainly about protection of ball speed on off-centre hits. Again, we can see why this is a good thing on drivers and putters.
Why do putts go short?
It is also not going to set off straight. So when golfers leave putts short it can often be because they haven’t struck it out of the middle of the face.
What Is MOI In Golf Clubs And Why It Matters
The engineering that goes into modern drivers is just mind-blowing, clubs are developed more like formula one cars than golf clubs these days. Manufacturers genuinely use wind-tunnels to test the perfect aerodynamics of the head.
What Exactly Is MOI?
During those microseconds of impact during the golf swing, your clubface twists. If you hit it out the middle it doesn’t twist but off-centre hits can cause pronounced twisting. That movement can contribute to wild shot shapes like snap hooks and slices.
How Is It Measured?
The USGA has a limit on MOI of 6000 grams per centimetres squared. If you look at the units there, you can start to get an idea of how this is measured. MOI is a measure of the force required to make an object rotate around an axis.
How Does it Affect Performance?
The higher the MOI the more forgiving the club. We’ve already established this, however, there is no such thing as a free lunch, as they say, so something must be lost for this gain. In general, as MOI increases, distance decreases.
High vs. Low MOI Pros and Cons
High MOI means more fairways hit with the cost of distance. Low MOI means more distance but reduced control of the ball on off-centre hits. If you are playing a low MOI driver your off-centre hits will become wilder shot shapes and misses.
Who Should Use High MOI?
High MOI is best for golfers who really need help to with forgiveness, players who find it hard to hit their clubs out the middle.
Who Should Use Low MOI?
Players who are consistently good ball strikers will benefit from low MOI.
What does MOI mean in golf?
The acronym "MOI" stands for "moment of inertia," and in golf MOI is a measurement of a club's resistance to twisting.
What is the MOI of a golf club?
MOI of the whole club around the golfer: As stated earlier, the whole golf club also has an MOI. The longer the club, the heavier the head, the heavier the total weight of the head, shaft and grip added together, the higher the MOI will be for the whole club.
Why is a higher MOI clubhead more resistant to twisting?
But if the moment of inertia can be increased, the club becomes more resistant to twisting. Therefore, a higher-MOI clubhead will twist less on off-center strikes than a lower-MOI one, meaning less loss of distance.
How to determine MOI?
Remember, MOI has to first be defined by identifying what axis the object is rotating around. There is an MOI for the whole golf club which, when swung, is "rotated" around the golfer during the swing. There are also three different MOIs that can be measured for the clubhead itself.
Why is MOI important in golf?
The MOI of the club is important to matching the swing feel of all the clubs in the bag. Clubfitting theory states that if all clubs in a set are made to have the same, identical MOI, the golfer will be more consistent because each club will require the same effort to swing.
What is swingweight in golf?
Swingweight is an expression of the ratio of the weight in the grip end of the club to the weight in the rest of the club on down to the clubhead. Swingweight-matched golf clubs are not matched for MOI, but come relatively close to MOI matching.
What does higher MOI mean?
Higher MOI equals more resistance to the object being rotated around an axis; lower MOI equals less resistance to the object rotating around an axis. Or, in plainer English: Higher MOI equals more forgiveness on off-center strikes with your golf club; lower MOI equals less forgiveness on off-center strikes.
High and Low MOI – What Is Better for You?
When one thing works for someone doesn’t mean everyone’s going to benefit from it. High MOI may be one of the prerequisites for the golf club to be highly forgiving but then NOT ALL players want their clubs to be that forgiving.
MOI In Putter
At the risk of sounding conceited, I’m still going to mention that I consider myself to be a veteran golfer at this point. And I have my years and years of Tournament golfing experience to vouch for that.
How Do Manufacturers of Golf Clubs Boost MOI?
The most common and effective approach to increase MOI – placing weight around the perimeter (edges) of the clubhead. With super game improvement irons, this is exactly what makes them magnanimously forgiving.
Should MOI Affect How You Choose Your Golf Clubs? (if yes, then how much?)
Ask yourself one very simple question at this point… what’s your biggest concern with your game currently? Is it not being able to hit accurate, consistent shots? In that case, high MOI plays a crucial role when it comes to what golf clubs to purchase.
Commonly Asked Questions – Moment of Inertia (MOI)
CG or COG means Center of Gravity. MOI means Moment of Inertia. The former controls launch and spin conditions. When CG is placed farther back and lower, it increases MOI and leads to a higher launch. In simpler words, more forgiveness on off-center shots.
What does MOI mean in golf?
What does moment of inertia (MOI) mean for golf clubs? If you're buying golf clubs, you're going to hear a lot about moment of inertia, or MOI, from the people selling you equipment. And that's for good reason. Moment of inertia is very important to a golf club's performance. In physics terms, moment of inertia is a measure ...
Why does MOI go higher in golf?
MOI goes higher when a golf club has more of its weight (which is , technically , a function of gravity's effect on mass) on the extremes of the golf club. In golf speak, that means "perimeter weighting.". By moving weight to the outside edges of the club, particularly on the club face, there's more support for off-center hits. ...
What is the moment of inertia of a golf club?
In physics terms, moment of inertia is a measure of the golf club's resistance to twisting at impact. There are actually lots of measures of moment of inertia, detecting the resistance to twisting in every which direction.
Does a golf club have an off center strike?
Quite simply, the golf club isn 't build to support an off-center strike as well as it does when you pure it. That makes sense. So golf club manufacturers are always trying to offer a higher moment of inertia rating, so as to give a golfer more protection on off-center hits.
What is MOI in golf?
MOI (Moment of Inertia) It will be easier to understand MOI if you think of it as an MOF (Measure of Forgiveness). Moment of Inertia is a measure of a body’s resistance to angular acceleration (twisting). In golf, MOI comes most into play on imperfect contact, when the ball and the clubface meet someplace other than the sweet spot.
What does restricting MOI mean?
Make no mistake – this is what restricting MOI means. The forgiveness built into a club means much less to the pros than it does to us; if this were not true, pros would use perimeter-weighted irons instead of blades. They don’t need the measure of forgiveness the way we do.
Is distance dependent on MOI?
Bigger does not mean longer, though it generally means more forgiving. Distance is not size dependent, or dependent on MOI. COR (Coefficient of Restitution), or spring like effect, is to some degree, but most clubs are already at the COR limit, and this is most effective when impact occurs exactly on the sweet spot.
How is MOI changed?
MOI is improved by moving weight away from the center of gravity of the club. This helps the clubhead to resist the twist.
Is MOI only found in Drivers?
MOI can be measured in all clubs. PXG’s new Battle Ready Putters are fully optimized, high MOI clubs – ideal when you need to close out on the green.
