What is m.s−1 ?

m.s1m.s^{-1} (meters per second) is a unit of speed or velocity in the International System of Units (SI). It indicates how many meters an object travels in one second.

1 m.s1=1 m/s1~m.s^{-1} = 1~m/s


For example, if an object is moving at a speed of 5m.s15 m.s^{-1}, it means that the object covers a distance of 5 meters every second. This unit is used commonly in physics and engineering to describe the rate of motion of objects.
