The vortex occures behind the plane where the airflow that has been disrupted by the plane passing through it comes back together. It is this effect felt when you stand on a road side and a large vehicle passes you, some second laters you feel the wind (vortex) hit you
A whirlpool is a kind of vortex. More specifically, a whirlpool is a vortex in water that can form from interacting currents. Different types of vortex can occur in air, water, or just about any liquid or gas.
drag is minimized by aerofoil shape. drag is a force acts on aircraft to minimize speed
Drag
no, its part of profile drag. due to roughness, skin friction increases which affects the drag. drag can also be increased by changing the shape or by introduction of active/passiv flow control devices like vortex generators.
yes. the flaps increase drag which slows the plane down.
Frontal Plane
In which plane does pronation and supination of the forearm occur?
Yes. This is part of what is called wake turbulence.
the flaps on a plane increase drag and they create lift so the piolt can fly the plane at a lower speed.
Two things: first, friction between the outside of the plane and the air it's passing through. Second, turbulence in the air will drag on the plane.

Drag is simply an external force that affects the motion of airplanes and offers resistance to the motion of the plane.Drag force of a flying plane is compensated by the weight of the plane and the the the forward motion.
