Hi guys. I just got a general question.
I learned about impulse today in class, and I just wonder why it exists?
Impulse is defined as "the change in momentum", but momentum is always conserved in elastic collision.
So if momentum is conserved, why there is a change in momentum?
I am so confused. I will appreciate your help!
