Problem
A student sketches three graphs for an object they claim is moving with constant, non-zero acceleration: (i) a position–time graph that is a parabola opening upward; (ii) a velocity–time graph that is a horizontal line above the time axis; (iii) an acceleration–time graph that is a horizontal line above the time axis. Identify which graph is inconsistent with the other two and briefly state why.
