 |  Re: Need an aerodynamics guru to help me out! Please!
There's very little energy lost to heat generation. Most of the energy "loss" is due to acceleration of air (kinetic and pressure energy, not thermal). Work was done on the air to accelerate it, and is equal to the integral of [drag_force(s) ds] (where s is the path of the object). As the object gets close to the ground, the air increases in pressure, and accelerates outwards.
