The
newton second (symbol
N s or
N·s) is the derived
SI unit of
impulse and
momentum. It can also be expressed as the kilogram metre per second (kg·m/s). One newton second corresponds to a one
newton force applied for one
second. The
newton second is occasionally, colloquially, referred to as a "sNewton."
It can be used to identify the resultant velocity of a mass if a force accelerates the mass for a specific time interval.
