Golf is a real Science

Golf is a real Science is a short golf blog post that attempts to clear up any open questions you may have regarding the golf equipment jargon.

Companies will tend to baffle you with science, often abbreviating long words or creating a new language.

So, here goes! This is my attempt at making things a little easier for you to understand.

Golf is a real Science – Scientific jargon made easy


MOI – Moment of Inertia

The MOI is the measurement of the club’s resistance to twisting at impact. The higher the MOI the less twist. Less twist means more accuracy is gained at impact therefore there is more accuracy for the golfer on the course.

COG – Center of Gravity

The Center of Gravity in a golf club affects the launch angle and spin of the golf ball.


This refers to the degree of resilience of a golf ball. How much the ball squashes against the clubface at impact.


The Hosel is the hollow, cylindrical part of the clubhead where the shaft is attached. Also known as the neck of the club.

Loft Angle

The loft angle of a golf club is the angle created between the clubface and the ground. This angle is different on every club.

Dynamic Loft Angle

The dynamic loft refers to the amount of loft on the clubface at the precise time of impact.

Lie Angle

The lie angle is the angle between the shaft and the ground. This can be Upright, Flat or Standard depending on the individual golfer.

Leading Edge

The leading edge refers to the bottom edge of the clubface.


The bounce is the distance between the leading edge and the ground at the address. The bigger the gap the bigger the bounce.


Blades is the old name for a set of irons. Typically a modern blade is a thinner, knife-like iron. Not suited for beginners!

Cavity Back

A cavity back iron is one that the back of the clubhead has been scooped out leaving a huge cavity, hence the name.

Sweet Spot

The sweet spot is the best spot, on the clubface, to make contact with the ball. Often found just under the centre of the clubface. The sweet spot is getting bigger and bigger each year.

Face Balanced

This refers to some Putters. Balancing the club on one finger, by the shaft, the clubface should point upwards. (See below).

Cambered Sole

This relates to the curvature of the sole of the clubhead, from heel to toe and from front to back.

Centrifugal Force

Centrifugal force is the action or force created when a rotating body moves mass away from the centre.


The area of a putter sole that extends back from the clubface.


These are the lines on the clubface which have several uses. Just like car tyre treads they are there to allow the dispersion of water and debris away from the impact point. They also help you to control the ball and the amount of spin on the ball.


The furthest part of the club from the golfer also known as the toe end of the clubface. Just like a shoe, the clubhead has a ‘sole’, heel and a toe.


The heel of the club is the closest part of the clubface to the golfer. The heel is found below the hosel.


Commonly means the leading edge of the clubface is a certain distance behind the hosel.


In a nutshell, the swing-weight refers to how heavy the club feels when you swing it.

Shaft Flex

The shaft flex refers to the shaft’s ability to bend during the swing. The shaft flex is vital as it helps control distance and consistency. There are lots of different shafts & flexes to suit every golfer.

Golf is a real Science unless you know the complicated terms and can convert them into your own basic wording.
