Alright, my teacher has the classic case of here are the sheets go do them, don't ask me questions. Ive been good about picking up so far but i have 2 questions right now. 1) m/s^2 does this mean for every 2 seconds it does 1 meter value? I.E. 1/s^2 so does that mean every 2 seconds it goes 1 meter? 2) What is the difference between bearing and heading?
