Newton 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 information
Unit system	SI derived unit
Unit of	Impulse and momentum
Symbol	N s
Named after	Isaac Newton
In SI base units:	kg ⋅ m/s

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.

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

Definition

Momentum is given by the formula:

• p is the momentum in newton second (N s) or "kilogram meters per second" (kg·m/s)
• m is the mass in kilogram
• v is the velocity in meters per second (m/s)

N s = N s= kg m/s
