In classical mechanics, impulse (symbolized by J or Imp) is the change in momentum of an object. If the initial momentum of an object is p1, and a subsequent momentum is p2, the object has received an impulse J: Momentum is a vector quantity, so impulse is also a vector quantity.
Impulse in Physics is a term that is used to describe or quantify the effect of force acting over time to change the momentum of an object. It is represented by the symbol J and is usually expressed in Newton seconds or kg m/s.

OpenStax. Learning Objectives. By the end of this section, you will be able to: Define impulse. Describe effects of impulses in everyday life. Determine the average effective force using graphical representation. Calculate average force and impulse given mass, velocity, and time.
The idea here is that you can calculate the impulse on the object even if you don’t know the details of the force as a function of time; you only need the average force. In fact, though, the process is usually reversed: You determine the impulse (by measurement or calculation) and then calculate the average force that caused that impulse.
Discover the fundamentals of impulse in physics, including its definition, formula, practical examples, and real-world applications. Learn how impulse affects motion and momentum in this comprehensive guide.
Impulse is a vector quantity; an impulse of, say, −(10 N • s) \(\hat{i}\) is very different from an impulse of +(10 N • s) \(\hat{i}\); they cause completely opposite changes of momentum. An impulse does not cause momentum; rather, it causes a change in the momentum of an object.
F net Δ t F net Δ t is known as impulse and this equation is known as the impulse-momentum theorem. From the equation, we see that the impulse equals the average net external force multiplied by the time this force acts. It is equal to the change in momentum.
Collisions, explosions and impulse Impulse Momentum, kinetic energy and impulse can be used to analyse collisions between objects such as vehicles or balls. Forces and the final velocity of...
Explain what an impulse is, physically. Describe what an impulse does. Relate impulses to collisions. Apply the impulse-momentum theorem to solve problems. We have defined momentum to be the product of mass and velocity.
