Metre per second squared
From Wikipedia, the free encyclopedia
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. 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.
To clarify this a bit further, one meter per second squared means, that if an object is accelarating at 1 m/s2 speed, it will go at 5 m/s speed after 5 seconds (etc.) accordingly.
Since the newton equals one kilogram metre per second squared, the unit can also be written as the newton per kilogram, N×kg-1, or N/kg.[1]
