The Anatomy of a Perfect Free-Kick

In Free-Kick Curl the wall jumps to roughly 40% of bar height and the sweet flight needs power between 60% and 80% with off-centre aim. Below 60% the ball drops into the wall; above 80% it clears the bar. The same physics explains real free-kicks — the greats are not kicking harder, they are kicking smarter inside a narrow power window.
