Launch Monitors Can Guide Practice Without Running It

Attack Angle 1 article
Attack angle is the vertical direction of clubhead movement at impact, usually expressed as upward or downward relative to the ground. It characterizes the swing delivery rather than the flight angle of the ball. A positive driver attack angle and a descending iron strike describe different impact approaches, but neither value alone determines the resulting launch or spin. Whether clubhead attack angle applies depends on the exact equipment or software version being discussed.
