SwingLab: See Your Golf Swing

Your swing is science.

Almost everything in golf is physics. Why your backswing-to-downswing ratio should be 3:1. Why holding the wrist hinge longer makes the club head faster. Why an open face sends the ball slicing. Don't memorise formulas — see it, move it, understand it. Then practise what you learned.

■ Theory — physics you can touch
· The Pendulum: isochronism, and why tempo stays constant at any swing size
· Tempo 3:1: the constant-acceleration downswing that gravity builds for you
· Impact & Distance: per-club ball flight, and how face strike bends the shot
· Ground Reaction Force: how pushing the ground becomes club head speed
· Shot Shape & Slice: why a slice happens — diagnose it by face and path
· Putting Distance: understand the distance errors behind three-putts

■ Training — practise what you learned
· Camera posture check: film yourself side-on and see your spine and knee angles at address in real time. Video is never saved or sent — it is processed on your phone only.
· 3:1 tempo metronome: groove a backswing of 3 and a downswing of 1 to the beat
· Release timing game: tap the moment to unhinge your wrists in a slow-motion downswing
· Carry challenge: tune club head speed, loft and attack angle to land on the target
· Practice records: watch your scores trend as the feel settles in

Every simulation runs on real physics equations, calibrated against tour measurement data.
