1)anyone tells me what is the differences between impulse and impulsive force?? 2) impulsive force = force X time momentum = mass X change in velocity impulse force = momentum. i know why but i dont understand why impulsive force is same as momemtum, if i want to decribe something about the punch of the frighter, i should say impulsive force ?? and when i should say it is momentum not impulsive force??
