How can you relate a force with the change of momentum of a body

Force is a measure of the change of momentum over time. It can be written as F = mass x change in velocity / time. In practical terms, the momentum of an object increases when a force is acting upon it, because the force is causing it to accelerate, and to have an increase in velocity.

HEY!!!
linear momentum of a body =
mass × velocity
but when force is applied on a moving body it's velocity changes .Due to change in velocity of body it's momentum also changes...
So,
initial momentum =mass(m) ×inital velocity(u)
final momentum =mass(m)× final velocity(v)
So...
Change in momentum of body in t seconds
=mv-mu
=m(v-u)
So....
rate of change of momentum
=change in momentum /time
=m(v-u)/t
but acceleration=v-u /t
so...
rate of change of momentum =ma
