Which quantity is measured in metre per second in SI system?

The quantity measured in meters per second (m/s) in the International System of Units (SI) is velocity. Velocity is a vector quantity that describes the rate of change of an object's position with respect to time. It indicates both the speed of the object and the direction of its motion. The SI unit for velocity is meters per second (m/s), where one meter per second is equal to the distance travelled in meters divided by the time taken in seconds.

In the International System of Units (SI), meters per second (m/s) is used to quantify the speed and direction of motion. This measurement, termed velocity, indicates how quickly an object changes its position relative to time and in which direction it moves.
