Question

Q.21 kg×m/s is the unit of:

Answer 1

Answer:

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-metre per second (kg⋅m/s).

Answer 2

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).

SI unit: kilogram meter per second kg⋅m/s

Other units: slug⋅ft/s

Dimension: MLT−1

Common symbols: p, p
