Question #210403
if in the graph of displacement vs time's written that final position is 0 displacement. And in the velocity vs time graph, it's written that final velocity is minus. while we know that velocity is displacement's divided by time, when displacement is 0 velocity should be 0 too, EXPLAIN WHY VELOCITY IS MINUS INSTEAD OF 0
Expert's answer
When we travel across circle in some moment the displacement is zero (the same point). But the speed always was nonzero and its direction is negative.
