Its shape - it's designed so that, as it spins, it pushes air (or water) behind it. This 'pushing' action provides thrust for the aircraft (or boat) - moving the vessel forward.
With a propeller.
No, the propeller will only work if the engine is running.
A propeller is connected to a drive shaft which is connected to an engine that runs the same way as a car
It propels.
the motor spins the propeller like a turbine. isn't it obvious, idiot .
It's the engine that makes the propeller go fast, not the number of blades.
It moves.
The pitch of the propeller causes this noise.
The curved shape of the propeller deflects airflow to it's rear. This is 'thrust' that propels an aircraft.
Where the gun fires through the propeller, the two are mechanically connected and timed so that the rounds will pass between the blades of the propeller.
what do u think hell no
A propeller is the object on the aircraft that rotates to produce thrust almost like a fan makes wind... it aims the wind behind it and pushes the aircraft forward
