Aerodynamic drag analysis of runners
Medicine & Science in Sports & Exercise, 1976 A model is presented for the determination of aerodynamic drag forces on runners. The model consists of a series of conjugated circular cylinders, to stimulate the trunk and appendages, and a sphere to stimulate the head. Results are presented for three runners representing respectively, adult American males in the 2.5, 50 and 97.5 percentiles of the ...

That's a Drag: The Effects of Drag Forces
Undergraduate Journal of Mathematical Modeling: One + Two, 2009 Drag is a force that opposes motion due to an object's shape, material, and speed. This project defined what drag force is, derived the governing equation for drag and listed some applications of drag forces.
