Newton-second (symbol Ns, N s or N·s) is the derived SI unit of impulse and momentum. One Newton-second corresponds to a one newton force applied for one second.

\vec F \cdot t = m \vec v

It can be used to identify the resultant velocity of a mass if a force accelerates the mass for a specific time interval.
