Aerodynamics: The study of the behavior of ... Knuckling effect: A phenomenon where a ball moves unpredictably due to a lack of spin, often resulting in erratic flight paths.

For example, one study utilized flight data to identify a nonlinear, quasi-steady spin aerodynamic model for a fixed-wing aircraft. This model was developed using advanced data collection ...

The key to excelling at the Australian Open is mastering the art of ball spin. Players like Novak Djokovic and Rafael Nadal ...
