THE DEFINITIONOF IMPULSE IS THE PRODUCT OF FORCE APPLIED AND THE TIME TAKEN
I=F*T
BUT F=ma
if the initial velocity pf the body is u and the final velocity of the body is v then acceleration a=v-u/t
therefore
F=m(v-u)/t
therefore substituting in the impulse equation
I=mv-mu
I=m(v-u)
THEREFORE IMPULSE IS NOTHING BUT CHANGE IN THE MOMENTUM OF THE BODY.................!!
