metre per second Meaning
Definition: Metre per second (m/s) is a unit of measurement that quantifies speed or velocity. It represents the distance traveled in meters over a period of time measured in seconds. Specifically, it describes how many meters are covered in one second.
Usage: The term is commonly used in physics, engineering, and other sciences to express the rate of motion. For example, a car traveling at 10 m/s is moving at a speed that allows it to cover 10 meters in each second. The unit can apply to various contexts, from calculating the speed of an athlete running to the velocity of objects in motion in physics problems.
Etymology: The term “metre” derives from the French word “mètre,” which comes from the Greek word “metron” (μέτρον), meaning “measure”. The abbreviation “m” stands for metre, which is a base unit in the International System of Units (SI). The term “per” indicates division, and “second” comes from the Latin “secundus,” meaning “following” or “second,” referring to the time unit.

Synonyms:
- Speed (in a contextual sense)
- Velocity (in a more specific sense related to direction)
Antonyms:
- None directly, but it is often contrasted with “standing still” or “stationary,” indicating a speed of 0 m/s.
Overall, “metre per second” is a fundamental unit essential for understanding and describing motion in scientific contexts.
- The car was traveling at a speed of 20 metres per second when it approached the intersection.
- The runner completed the 100-meter dash in just under ten seconds, reaching a speed of approximately 10 metres per second.
