What is an impact in golf?

Definition

The precise moment when the club face contacts the golf ball, representing the culmination of the entire swing motion where all swing elements must coordinate perfectly. Impact lasts only milliseconds but determines all ball flight characteristics including direction, distance, trajectory, and spin. Understanding impact dynamics helps golfers appreciate the precision required for consistent golf and the importance of proper swing mechanics. Modern high-speed photography and launch monitor technology have revealed the complexity of impact mechanics. Optimizing impact conditions is the primary goal of all swing instruction and practice.
