An impulsive force is a very great force acting for a very short time on a body, so that the change in the position of the body during the time the force acts on it may be neglected.
The impulsive force is much stronger than any other force available at that point of time.
It is defined as the rate of change of momentum
Impulse =mv-mu(momentum change)
Impulsive force=Impulse/time
Example: a hammer, the collision of two billiard balls
