The newton second (also newton-second, symbol N s or N·s)[1] is the derived SI unit of impulse. It is dimensionally equivalent to the momentum unit kilogram meter per second (kg·m/s). One newton second corresponds to a one-newton force applied for one second.

For two objects moving with the same velocity (v), the object with the greater mass (m) will have the greater momentum (p).
Unit information
Unit system SI derived unit
Unit of Impulse and momentum
Symbol N s 
Named after Isaac Newton
In SI base units: kgm/s

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

DefinitionEdit

Momentum is given by the formula:

 
N s = N  s= kg   m/s
