Understanding Ball Flight Laws

For decades, golf instruction was built on a misunderstanding. The "old" ball flight laws said the ball starts in the direction the club is swinging. The truth — confirmed by launch monitor data — is almost the opposite.

The Modern Ball Flight Laws

The ball starts predominantly in the direction the clubface is pointing at impact. The path of the club through the hitting zone determines the curvature of the shot. This is a fundamental shift from what many golfers were taught.

Face Angle Controls Starting Direction

Approximately 75–85% of the ball's initial direction comes from the face angle at impact. If your face is 5° open to your target at impact, the ball will start 3–4° right of target (for a right-handed golfer), regardless of your swing path.

Path-to-Face Relationship Creates Curvature

If your path is 5° right and your face is 5° right — the ball starts right and goes straight (no relative difference). If your path is 5° right but your face is square — the ball starts right but curves left. The relationship between path and face determines the shape.

Diagnosing Your Miss

Ball starts left, curves further left: face closed to path. Fix your grip.
Ball starts right, curves further right: face open to path. Fix your grip and impact position.
Ball starts straight but curves: path and face not aligned.
