Actually, the applied force and transferred energy, in this case, are velocity dependent according to the
drag equation. The fluid density, ball area, and drag coefficient are fixed (unless you are using a very narrow stream of air, which would would change the area parameter). As a result, velocity really is the only relevant property of the airflow.
