The forward motion of the ship through the water, is provided by the propellor.
My boat was marooned as an old rope got wrapped around the propeller.

Weight savings.
The model airplane's propeller made a whir as it went by.
dont know
A propeller vehicle uses air resistance to generate forward thrust. As the propeller spins, it creates a pressure difference between the front and back of the propeller, causing the vehicle to move forward. The air resistance acts against the motion of the propeller, helping to propel the vehicle forward.
This experiment will demonstrate the use of magnets to propel our model rocket across the parking lot. I hope that my repairs to the propeller will successfully propel us across the lake to safety.
get naked and twirl in circles
On water or marshes. Also in the air.
They both (some airplanes do) use propeller's.
1) keyed propeller and 2) keyless propeller................... they have further classificaton 1.fixed pitch propeller 2.controllable pitch propeller 3.directional pitch propeller
Some ships do. It is called a reduction gear and takes power from the engine and transmits it to the shaft and propeller. Other ships use direct drive, electric motors, steam or other schemes to power the propeller.
