Impulse. In classical mechanics, the impulse of the resultant external force on an object is equal to the change in its momentum, which is called the momentum theorem. Unlike momentum, which is a state quantity, impulse is a process quantity. The impulse of a constant force refers to the product of the force and its action time. Impulse is a physical quantity that describes the cumulative effect of a particle over a period of time, and is the reason for changing the mechanical motion state of the particle.
