It is the change of rate of momentum

Impulse is the integral of force over time, it is measured in Newton-seconds. For instance a force of one Newton applied over one second will change the momentum, a force of two Newton's applied over half of a second will have a similar effect.

For rigid body collisions we take this to its limit and apply an infinite force over an infinitesimally small time. This impulse is equal to the change in momentum of the colliding objects. Because we are talking about forces here, Newton's third law applies, and the impulse on the colliding objects will be equal and opposite.

impulse = m(vf- vi)

In simple words: Impulse- A form of fast-moving electrical messages

Can a moving object have impulse in itself?

No. Impulse is a change in momentum and so a moving object with a constant velocity has no impulse. in real life air resistance imparts an impulse to the object slowing it down but the object cannot really be said to have impulse
