What is impulse of force? Write its unit and dimension.

(N/A) Impulse of a force is defined as the product of the average force acting on an object and the time interval for which it acts.
Mathematically,$Impulse (J) = F_{avg} \times \Delta t$.
It is also equal to the change in momentum of the object,i.e.,$J = \Delta p = m(v - u)$.
Unit: The $SI$ unit of impulse is $Newton-second$ $(N \cdot s)$ or $kilogram-meter$ per second $(kg \cdot m/s)$.
Dimension: Since impulse is equal to change in momentum $(p = mv)$,its dimension is $[M^1 L^1 T^{-1}]$.
