Here's a page for you to explore the relative velocity between an aircraft in flight, the ground, and the air through which the airplane moves. In this animation, the white clouds move relative to the ground at the wind speed, the airplane moves relative to the ground at the ground speed, and the airplane moves relative to the air at the airspeed. Airspeed is the important velocity for the generation of lift and drag. More information about these velocities is given on the Relative Velocity Slide.
