Impulsive Force is a force that acts on a body for short interval of time making a change in its velocity or so called momentum; or the force that two colliding bodies exert on one another acts only for a short time, giving a brief but strong push. This force is called an impulsive force.The impulsive force is much stronger than any other force available at that point of time and acts on an object for a very short interval during collision or explosion.

Examples are:

1. When a batsman plays a shot for six, a force acts on a ball through a bat for short interval of time. We call that force, an impulsive force.

2. When a bullet strikes a glass, an impulsive force acts on the glass.
