Golf looks like feel and luck. Underneath it is physics you can measure: a ball with a fixed mass and a dimpled surface, a club delivering energy at a known speed and angle, and a body trying to repeat a motion. The more of that you understand, the less the game feels like superstition.
These notes start as seeds. Each one is a question I want to answer properly, with real sources, rather than the half-remembered version you hear on the range. They grow into full notes as I research them.
Ball flight and impact
- The Physics of Ball Flight - lift, drag, and why a dimpled ball flies twice as far as a smooth one.
- The Swing as a Kinetic Chain - how the body sequences ground to clubhead to deliver speed.
Planned (seeds to research)
These do not have notes yet. They are the next questions in line.
- Spin and the Magnus effect: how backspin creates lift and sidespin shapes a draw or fade.
- Smash factor: ball speed divided by clubhead speed, and why 1.50 is the driver ceiling.
- Launch and spin optimization: the launch-angle and spin-rate window for maximum carry.
- Strokes gained: the statistical model that replaced “fairways and greens” as the real scoreboard.
- Equipment physics: MOI, center of gravity, and what “forgiveness” actually means.
- Putting: green reading, gravity, and why most putts are missed on the low side.
Connections
The probability side of scoring (strokes gained) leans on statistics. The flight model is a clean applied case of forces and vectors.
