Newton-second

The newton-second (also newton second; symbol: N&sdot;s or N s) is the unit of impulse in the International System of Units (SI). It is dimensionally equivalent to the momentum unit kilogram-metre per second (kg&sdot;m/s). One newton-second corresponds to a one-newton force applied for one second.


 * $$\vec F \cdot t = \Delta m \vec v$$

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

Definition
Momentum is given by the formula:
 * $$\mathbf{p} = m \mathbf{v},$$


 * $$\mathbf{p}$$ is the momentum in newton-seconds (N&sdot;s) or "kilogram-metres per second" (kg&sdot;m/s)
 * $$m$$ is the mass in kilograms (kg)
 * $$\mathbf{v}$$ is the velocity in metres per second (m/s)
