Unit of Speed
Unit of Speed is meters per second or m/s. Speed is a physical quantity that measures the distance travelled by an entity per unit of time. The most commonly used units for speed are meters per second (m/s), kilometres per hour (km/h) and miles per hour (mph). Speed and Velocity are the same physical quantity except for the difference that velocity is a vector quantity and speed is a scalar quantity, so speed and velocity units are the same.
