Question

What is the unit of impulse ?

Answer 1

1. Impulse is used to describe the effect of force acting over time to change the momentum of an object.
2. It is represented by $J$.
3. The newton second ($N.s$) is the SI unit of impulse.
4. The application of an impulse to an object, which is frequently in the same direction, results in an equal vector shift in its linear momentum.
5. The $Newton-second$ ($N.s$) is the SI impulse unit, and the $ki\log rammeterpersecond$ $(kg-m/s)$ is the dimensionally comparable momentum unit.
