Luckily, the impulse-momentum theorem is logically equivalent to the much more well-known concept of Newtons second law of motion (f=ma), which states: the change in momentum of an object equals the impulse applied to it. For our understanding, it can be simplified to the formula: Impulse (I) is defined as the integral of a force over the time interval for which it acts. To simplify, it measures the magnitudes of force applied and their duration and provides a sum of the total force. He is passionate about sports, cinema, astronomy, and sharing knowledge.
