integral of a force over the time interval for which it acts; term in classical mechanics

AI overview

An impulse is the total effect of a force applied over a period of time, calculated by multiplying the force by how long it acts. It matters in physics because it helps explain how forces change an object's motion, and it's a key concept in classical mechanics for understanding collisions and other interactions.
