Newton-second


The newton-second is the derived SI unit of impulse. It is dimensionally equivalent to the momentum unit kilogram-metre per second. One newton-second corresponds to a one-newton force applied for one second.
It can be used to identify the resultant velocity of a mass if a force accelerates the mass for a specific time interval.
