what is the si unit of momentum

The SI unit of momentum is kilogram meter per second (kg⋅m/s) . Momentum is defined as the product of mass and velocity, and it is a vector quantity that has both magnitude and direction. The unit of momentum is the product of the units of mass and velocity. In SI units, if the mass is in kilograms and the velocity is in meters per second, then the momentum is in kilogram meters per second (kg⋅m/s) . In the CGS system, if the mass is in grams and the velocity is in centimeters per second, then the momentum is in gram centimeters per second (g⋅cm/s) .
