Impulse #vec(I)# is a vector quantity that describes the effect of a fast varying force applied to an object for a short time:

The effect of an impulse on an object is a variation of its momentum #vec(p)=mvec(v)#:

#vec(I)=Deltavec(p)#

Every time you have a quick, rapid, fast interaction between objects you have impulse as in the following examples:
