A propeller is like a spinning wing. The airfoil shaped blades pull an airplane forward just as an airplane's wings lift it upward. The amount of thrust created by a propeller depends on how fast and at what angle its blades cut through the air. The propeller is generally powered by a combustion engine which fires pistons and turns the propeller.
wind turbines can be placed, and the spinning of the propeller turns some magnetic thing against a coil, producing electricity.
Prop wash is caused by a passing propeller driven aircraft. The spinning prop creates a vortex like wind that can be quite violent.
By the propeller, pulling itself through the air.
It is the opposite to the way how old airplanes were propelled. They use the propeller. When the propeller is exposed to the wind it rotates automatically. (Compare with the boat propeller and water turbine.)
The spelling "propellor" is a variant.The usual spelling is propeller (spinning blades to push or pull in air or water).
The spinning shaft from the engine to which the propeller is attached.

They both exist.
They both exist.
The propeller or the "prop" or "screw" is the device that propels the vessel through the water by spinning , this is different from a jet drive, which sucks in water and shoots it out to push the vessel through the water.
A pull propeller is more efficient due to the fact it is in clean/non turbulent air.
Reciprocating engines are very big engines. Instead of a motor just spinning the propeller, electric arms would move up and down circling around the propeller line spinning it. These kind of engines were used on the titanic.
a Propeller
No. A submarine's propeller relies on the water around it for something to push against. As space is a vacuum, the propeller would have nothing to push against, ergo the submarine would have no thrust.

Neither a spinning real or push button type reel are used in fly fishing.
