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 ■ More · Golf physics quiz (retry just the ones you missed) · Club data dictionary (animated trajectory overlay) · Physics fact cards No ads · Every feature free · Works fully offline. The camera is used only for the posture check. Every simulation runs on real physics equations, calibrated against tour measurement data. Note: an educational approximation model. Results will differ from a real launch monitor.
