Definition: A piston is a mechanical device that moves up and down or back and forth inside a cylinder. It is commonly used in engines and machines to create motion or pressure.
Usage Instructions:
Examples:
Basic Example: "The car’s engine has several pistons that help it run smoothly."
Advanced Example: "In a hydraulic system, the piston compresses fluid, which allows for powerful movement."

"Piston-like motion": This phrase can be used to describe any repetitive motion that resembles the up-and-down movement of a piston.
Summary:
A piston is an important part of many machines, especially engines, that helps create movement. It works by moving up and down or back and forth, and it can also be compared to other devices that create similar motions.
