Question

If $impulse=force\times time$, the SI unit of impulse is ______.

Answer 1

Hint: SI unit of a derived quantity can be calculated by substituting the SI unit of base quantities in the formula of derived quantity.
Prerequisite: SI unit of force and time

1. Impulse can be defined as a term that is used to quantify the effect of a force acting over a particular time to change the momentum of an object.
2. Mathematically, it can be given as $Impulse=Force\times Time$
3. So, the SI unit of impulse = SI unit of Force $\times$ SI unit of Time = $N\times s$

Thus, the SI unit of impulse is $N-s$.
