Basic question about drag

  1. Jul 10, 2006 #1
    Is air drag proportional to the speed or the speed squared? What data did you gather to support your answer?

    Can someone please provide me an explanation? Thx.

    type "air drag" into google

    or to narrow your focus try

    "air drag +wikipedia"

    without the quotes

    There's a basic governing equation for drag involving velocity, surface area and a couple of other variables. I've posted it here before, but since we're not supposed to just give out answers I'm not sure if I'm allowed to or not. To give you a hint - pressure is what gives an aircraft its lift as well as what causes its drag. Drag, being a force, is pressure multiplied by the area it acts upon. So if you know how velocity relates to pressure, you can get an understanding of how it relates to the drag force.
