Which of the following quantities are units of momentum? (there could be more than one correct choice.) a)n m b) kg s/m c) kg m/'s d)n-s 12 points] e) kg m2/s2

Answer : Units of momentum are :

1. Kg m/s

2. N-s

Explanation:

The momentum of an object is given by the product of its mass and velocity with which it is moving. Mathematically, it is given by :

P = mv

Where

m is in kilogram

v is in m/s

Option (1) : N-m = It is not a unit of momentum. It includes the product of force and distance.

Option (2) : Kg s/m = It is again not a unit of momentum.

Option (3) : Kg m/s =

Since, p = mv

p = Kg × m/s

It can be the unit of momentum.

(4) Option (4) : N-s = The change in momentum is equal to the impulse applied on an object. It is given by the product of force and short duration of time. It can be the unit of momentum.

(5) Option (5) : Kg/m²/s² = It is not the unit of momentum.

Hence, the correct options are (c) and (d).
