The magnitude of a physical quantity is 6 Ns. What is this physical quantity?
Pressure
Force
Acceleration
Momentum
Momentum = mass × velocity
N = kg ms−1
Force = mass x acceleration
N = kg × ms−2
Hence, momentum can be expressed in Ns.
The magnitude of a physical quantity is expressed as
Physical quantity = ___ × unit
