What key data points describe the launch of a golf ball?

The launch of a golf ball is critically analyzed through various metrics that directly impact its trajectory and performance. The key data points that effectively encapsulate this phenomenon include the spin axis, spin rate, launch angle, direction, speed, and smash factor.

To break this down, the spin axis refers to the orientation of the rotation of the ball, which affects its flight pattern and stability in the air. The spin rate quantifies how fast the ball is spinning upon leaving the clubface, contributing to its lift and control.

Launch angle is crucial because it determines how high the ball will rise and how long it will stay in the air. Direction pertains to where the ball is intended to go, while speed relates to the initial velocity of the ball immediately after impact, influencing distance. The smash factor, which is the ratio of ball speed to clubhead speed, helps gauge the efficiency of the energy transfer from the club to the ball.

In contrast, while club speed and angle are relevant to the overall performance, they do not provide a comprehensive view of the launch conditions. Temperature and humidity can affect ball performance but are not primary data points regarding the launch itself. The player's stance and grip are also important for overall performance but do not define the physical flight
