Kilogram metre per second

newton second
For two objects moving with the same velocity (v), the object with the greater mass (m) will have the greater momentum (p).

Unit of	Impulse and momentum
Symbol	Ns
Named after	Isaac Newton
In SI base units:	kg ⋅ m/s

The newton second (also newton-second, symbol Ns or N·s) is the derived SI unit of impulse. It is dimensionally equivalent to the momentum unit kilogram metre per second (kg·m/s). 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.

Momentum is given by the formula:

Below, the magnitudes of some momenta are given for various masses and speeds (magnitudes of velocity).
