The metre (or meter) per second squared is the SI derived unit of acceleration. It is a measure of magnitude and can be a scalar measure or, when associated with a direction, a vector, for example by having sign positive or negative. The unit is written in symbols as m/s², m·s⁻², or m s⁻². It may be better understood when phrased as "metre per second per second"—in other words, the increase in speed (in metres per second) that is achieved each second. SI derived units are part of the SI system of measurement units and are derived from the seven SI base units. ... Acceleration is the time rate of change of velocity and/or direction, and at any point on a velocity-time graph, it is given by the slope of the tangent to the curve at that point. ...

Metre per second (U.S. spelling: meter per second) is an SI derived unit of both speed (scalar) and velocity (vector), defined by distance in metres divided by time in seconds. ...

The SI derived unit of force, the newton, is one kilogram metre per second squared, meaning that a force of one newton will give an acceleration of one metre per second squared to a mass of one kilogram. This is an example of Newton's second law (see Newton's laws of motion). So, the metre per second squared is the same unit as the newton per kilogram; to give an everyday example, one g (see g-force) is approximately 9.8 N/kg, which is the same as 9.8 m s⁻².
