The position-vs-time graph shows an object's motion. Between t = 2 s and t = 6 s, which best describes the object's motion?
AThe object is accelerating.
BThe object is moving at constant velocity.
CThe object is at rest.
DThe object is moving backward.
Explanation
📌 A horizontal line on a position-vs-time graph means position is not changing — the object is stationary (at rest). Distractor A confuses horizontal line with acceleration; B confuses horizontal with constant motion; D confuses horizontal (no motion) with negative slope (backward motion).
