impulse means?

Impulse (symbolized by J or Imp) is the change in linear momentum of a body. It may be defined or calculated as the of the average force multiplied by the time over which the force is exerted. Impulse is a vector quantity since it is the result of integrating force, a vector quantity, over time. The SI unit of impulse is the N-s or, in base units, the kilogram meter per second (kg·m/s).

The quantity of an impulse is average force × time interval, or :-

Impulse is defined as a force multiplied by the amount of time it acts over. In calculus terms, the impulse can be calculated as the integral of force with respect to time. Alternately, impulse can be calculated as the difference in momentum between two given instances.
