The product of average force and the time it is exerted is called the impulse of force. From Newton's second law - (Given in the first image)
the impulse of force can be extracted and found to be equal to the change in momentum of an object provided the mass is constant: (given in the second image)
The main utility of the concept is in the study of the average impact force during collisions. For collisions, the mass and change in velocity are often readily measured, but the force during the collision is not. If the time of collision can be measured, then the average force of impact can be calculated.
