Question

1. Which option is not true about momentum? a. Momentum is a vector quantity b. The Unit of Momentum is kg m/s c. Momentum is a scalar quantity d. When two bodies acts on each other and no external force is acting on the system, then the momentum remains constant

Answer 1

Answer:

(c) option is incorrect

Explanation:

Momentum is not a scalar quantity it is vector quantity

This is because, momentum= mass*velocity

And scale of momentum is kg m/s. Kg is for mass and m/s is for velocity

And as velocity is direct proportional to momentum and velocity is vector quantity, so momentum is also vector quantity.
