Answer
The object is stationary
Explanation
A horizontal line indicates that there is no change in distance over time, meaning the object is not moving.
Common mistake
Misinterpreting Gradient
Students often think that a steeper gradient on a distance-time graph indicates a longer distance rather than a greater speed.
Remind students that the gradient represents speed; a steeper gradient means the object is moving faster, not just covering more distance.
