1. A method for determining a speed of a ball used for an athletic activity, the method comprising:
- sensing acceleration data, using a sensor module coupled to the ball;
determining a drag force applied to the ball, based on the acceleration data;
comparing the drag force with a drag profile that expresses drag as a function of ball speed, wherein the drag profile is based on experimental data; and
determining the speed of the ball based on the comparison.
