My textbook states that "The velocity has the same direction as the displacement". I feel this statement is incorrect. Keeping in one dimension, let's say that I move in the +ve direction at velocity v for some time t. My displacement is vt which points in the +ve direction. However I then stop and move back to my starting point at velocity -v for time t1 < t. My displacement is now vt - vt1, which still points in the +ve direction, however my velocity is -ve. Is my reasoning correct? I don't know if the book is trying to mean something else, or what. Thank you! EDIT: I believe the book may be talking about average velocity and not instantaneous velocity. So perhaps it's correct in that sense???
