kilogram metre per second
|kilogram metre per second||kg m s−1||momentum|
The kilogram metre per second, symbol kg m s−1, is the SI coherent derived unit of momentum.
The kilogram metre per second, is equivalent to the unit newton second, symbol N s.
In Newtonian mechanics, momentum, or linear momentum, is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction in three-dimensional space.
If m is an object’s mass and v is its velocity (a vector), then the momentum p is:
Newton’s second law of motion states that a body’s rate of change in momentum is equal to the net force acting on it.
