Newton second(Redirected from Kilogram metre per second)
The newton second (also newton-second, symbol N s or N·s) 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.
|Unit system||SI derived unit|
|Unit of||Impulse and momentum|
|Named after||Isaac Newton|
|In SI base units:||kg ⋅ m/s|
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:
- 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
