Meters per second (m/s) is a unit of measurement used to express speed or velocity. It indicates how many meters an object travels in one second. For example, if a car is moving at 20 m/s, it means the car covers 20 meters every second. This unit is commonly used in various fields, including physics and engineering, to quantify the speed of moving objects like cars, bicycles, and airplanes. Understanding m/s helps in calculating travel times and comparing speeds, making it an essential concept in both everyday life and scientific studies.
