please write down the three newton's laws of motion in both translation and angular forms, including their "equivalent" expressions of newton's second law. what are the assumptions for their application in classic mechanics? are those "equivalent" forms really equivalent? why? this is from my mid-term. i don't know how to answer this though it seems simple. in fact, i don't really understand what the question is about. especially the ""equivalent" part. can anyone please help me with it? Thank you.
