I have a question about impulse. So, impulse equals change in momentum or average force * change in time. So I have a couple of questions actually. Does impulse only apply for extremely small changes in time? Like if a car crashed and was in contact with something for a second before it stopped, is that still considered 'impulse'? Also, via the formula, the impulse becomes greater when the change in time becomes greater. But I thought there was a larger impulse when time was smaller? If anyone could help clear these up for me that would be great. Thanks :)
