Newton's experiments on drag were through air and fluids. He showed that drag on shot increases proportionately with the density of the air (or the fluid), cross sectional area, and the square of the speed. [9] Newton's experiments were only at low velocities to about 260 m/s (853 ft/s). [14] [15] [16]
