Lesson 1: Intro to Full Swing
This law refers to where the ball is struck on the clubface and heavily influences distance and direction.
Centeredness of Contact
Page 7
The only contact a golfer has with the club, this component affects traction and feel.
Grip
Page 68
This dynamic number is calculated as ball speed divided by clubhead speed.
Power Transfer Ratio (PTR) or Smash Factor
Page 78
This refers to the direction the clubface is pointing at impact.
Clubface angle
Page 8
This club component is critical for energy transfer and is described in terms like flex and kick point.
Shaft

This angle determines how upright or flat the clubhead sits at impact and is a key factor in directional control.
Lie angle
Page 75
This in-swing principle is the tilt and direction of travel of the inclined plane made by the club shaft during the swing.
Swing Plane

This measurement, influenced by head weight and shaft length, affects how heavy a club feels during the swing.
Swing weight

These four performance numbers are measured using a launch monitor.
ball speed, launch angle, spin rate, and PTR
Page 78
The combination of grip, aim, posture, and alignment are known as these types of fundamentals.
Pre-Swing Fundamentals Page 14
This performance number measures how much the club resists twisting on off-center hits.
Moment of Inertia

This technology-based tool captures data like launch angle, spin rate, and ball speed to assist in club fitting and swing analysis.
Launch Monitor
Pages 78-85
These are the student's stylistic choices, like open stance or cupped left wrist, within the swing model.

The term used to describe matching shafts to player's swing tempo.
Frequency Matching
Page 70
This data point, influenced by angle of attack and dynamic loft, helps determine whether a player is launching the ball efficiently with their driver.
