The impulse experienced by an object is equal to the net force acting on the object multiplied by the length of time the force acts (Δp = ΣFΔt). The same impulse can be caused by a large force acting for a short time, or a small force acting for a long time. 00:00 - Intro 00:52 - What is impulse? 03:54 - Which car gains more speed? 07:36 - Egg dropped on a stone breaks.
