Name the physical quantity whose unit is kg m/s.

Answer :

Momentum is defined to be ‘mass x velocity’, so it is a vector, in the same direction as the velocity.

Mass is measured in kilograms, kg, and velocity is measured in metres per second, m/s. These are the standard SI units of these quantities. Hence, the SI unit of momentum is kg m/s.
