In a distance-time graph, a STRAIGHT HORIZONTAL line means:
AThe object is at rest, with distance unchanging over time
BThe object moves with uniform velocity in one direction
CThe object accelerates with positive constant acceleration
DThe object decelerates and finally stops at the end
Answer & Solution
Correct answer: A. The object is at rest, with distance unchanging over time
A horizontal line in a distance-time graph means distance is unchanging over time, i.e. the object is at rest.
