Question

The unit used to measure distance is metres (m).
The unit used to measure time is seconds (s).
Speed = Distance / Time.
Hence the unit used to measure speed is m/s.
Now, momentum= mass x velocity.
Velocity has the same unit as that of speed. What would be the unit of momentum?

Answer 1

kgms-1

Explanation

∵ p=mv unit of m=kg

unit of v=ms-1

∴ unit of momentum

P=mV is kgms-1
