aerodynamic drag force

The net aerodynamic drag forces may be considered to act at a single point, called the center of pressure.

Even at moderate speeds, most power is spent in overcoming the aerodynamic drag force, which increases with the square of speed.

Of course, as soon as the ship begins to move, there will be hydro- and aerodynamic drag forces acting to slow the acceleration.

If we drop the paper, it will quickly reach a terminal velocity where the aerodynamic drag force pushing up is equal to the weight pulling down.

Birds fly in a flock for better lifting force whereas the race cars stay close for less total aerodynamic drag force.

Descending to the Earth using a parachute, which balances the force of gravity with an aerodynamic drag force (and with some parachutes, an additional lift force).

Increasing the velocity, the aerodynamic drag forces will begin to counteract the gravitational forces, causing the bed to expand in volume as the particles move away from each other.

The aerodynamic drag forces in such situations prevent them from producing full weightlessness, and thus a skydiver's "free fall" after reaching terminal velocity produces the sensation of the body's weight being supported on a cushion of air.
