Velocity Effects on Aerodynamic Forces

www.grc.nasa.gov/WWW/K-12/airplane/vel.html

... we find that lift and drag depend on the square of the velocity . The velocity used in the lift and drag equations is the relative velocity between an object and the flow. Since the aerodynamic force depends on the square of the velocity, ...

Aircraft Range - Constant Velocity + Text Only Site + Non-Flash Version + Contact Glenn As discussed on the airplane cruise slide, an airplane can maintain a constant speed and level flight, in which the lift is equal to the weight, and the ...

Terminal Velocity (gravity and drag)

www.grc.nasa.gov/WWW/K-12/rocket/termvr.html

... first law of motion. The constant vertical velocity is called the terminal velocity . Using algebra, we can determine the value of the terminal velocity. At terminal velocity: D = W Cd * r * V ^2 * A / 2 = W Solving for the vertical ...

Relative Velocity - Ground Reference
