A propeller is a device having a central hub and radial blades, each forming part of a helical plane. When it rotates in the water or in the air,
it generates pulling force to make the ship or aircraft move forward. The pull of a propeller is proportional to the product of the mass of the water or air it acts
on and the acceleration. For the most efficient propulsion, the mass should be large and the acceleration should be small.
