This is an old revision of the document!


In most real world situations, there is some kind of resistive force. Some of these are due to contact between solid objects (e.g., friction) and you will learn about those later. For now, we will consider resistive forces due to some kind of fluid, which might be air, water, oil, or even sand.

Laminar drag

Fdrag=bv

Fdrag=6πηv

Turbulent drag

Fdrag=cv2ˆv

Fdrag=12ρCdAv2ˆv
