A graph with horizontal axis time (seconds) and vertical axis position (meters). An orange line runs straight upward from 0 second zero meters. A concave blue line runs upward from the same point. Maia says that both lines on this position vs time graph show acceleration. Is she correct? Why or why not?
Sample Response: Maia is not correct because a straight line moving upwards on a position vs time graph has a constant slope, so it represents constant velocity. No change in velocity means no acceleration is taking place.
