That way of writing down vectors seems really useful :o. It's like the vector don't need to be drawn anymore and their actual location doesn't really matter anymore..?


There was a multiple choice question on my test saying something like: "Why don't we account for the internal forces of an object when calculating its momentum?" And then there were four things to select. I guessed a choice that said internal forces were somehow "conserved" too, but frankly I have no idea why '~'
