So Power = constant x distance x velocity^2/time = constant x velocity^3. The constant isn't really constant, as it changes with altitude, and can change with speed. The constant is defined by other paramters, and are shown in teh equation given by wiki Drag (physics) - Wikipedia, the free encyclopedia
