uses an engine / motor (or a sail :)
A boat typically uses a propeller as a device to move through water. The propeller works based on Newton's third law of motion, where the boat pushes water backwards with the propeller blades, causing an equal and opposite reaction that moves the boat forward. This action follows the principles of thermodynamics in terms of converting energy from the boat's engine into mechanical work to propel the boat forward.
The word paddle can be either a noun or a verb. A paddle is an instrument that is used to move a boat. If using the device, we are said to paddle the boat. She grabbed the other paddle to help row the boat. [noun use] The two of them paddle the boat clear of the rocks. [verb use]
