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 covers 20 meters every second. This unit is commonly used in physics and engineering to quantify motion. In everyday life, you might encounter meters per second when discussing the speed of athletes, vehicles, or even natural phenomena like wind. Understanding this measurement helps in comparing different speeds, such as the pace of a runner versus the speed of a bicycle.
