A propeller is a type of rotary wing that converts rotational motion into thrust, allowing vehicles like boats and airplanes to move through water or air. It consists of blades that spin around a central hub, creating differences in pressure on either side of the blades. This pressure difference generates lift in the case of aircraft or thrust in the case of boats, propelling them forward. Essentially, the propeller's design and rotation enable efficient movement through a fluid medium.
