Question

Define impulse and write its relation with momentum

Answer 1

impulse: product of force and time for which that force act

I=F×t

I=change in momentum

(where I stands for impulse)

Answer 2

Momentum is mass in motion, and any moving object can have momentum. An object's change in momentum is equal to its impulse. Impulse is a quantity of force times the time interval. Impulse is not equal to momentum itself; rather, it's the increase or decrease of an object's momentum.
