Speed at which a golfer swings a club. Specifically, how fast the clubhead is traveling at the moment it contacts the ball. Helps decide the optimal shaft flex for a golfer.

The point on a clubface that consistently generates the best contact with a ball. Typically located on or near the center of the clubface.

A golf ball's spin rate refers to the speed it spins on an axis while in flight, measured in revolutions per minute (rpm). A high-spin ball will carry longer and roll less and can be easier to dr [..]

Ball speed divided by club head speed. An optimal smash factor with a driver is said to be around 1.5.

Describes the force required to set a golf club in motion. A lower MOI means less force is needed to complete a swing (rotation), while a higher MOI means the club requires more force. Directly influe [..]

The angle, in degrees, of the clubface. Higher lofts naturally produce higher trajectories, while lower lofts produce lower-flying, longer shots.

The angle at which the ball leaves the ground after being struck.

The point where a shaft is fitted and secured into a clubhead.

Kickpoint, also called flex point or bend point, is the point along a shaft's length at which it exhibits the greatest amount of bend. The lower the kickpoint, the higher the ball trajectory.

"Handicap" refers to a numerical representation of a golfer's playing ability. The lower a golfer's handicap, the better the golfer is.
