Question
When the distance-time graph of an object is a curved line, it indicates that __________.
The correct answer is
The speed of the object is changing with time
Interpreting Curved Distance-Time Graphs
The distance-time graph plots the distance traveled by an object against time. The slope of this graph represents the object's speed.
- Constant Speed: A straight line on a distance-time graph (with a non-zero slope) indicates constant speed. The slope is constant.
- Stationary Object: A horizontal line indicates the object's distance from the reference point is not changing, meaning it is stationary (zero speed).
- Changing Speed: A curved line means the slope is continuously changing. This indicates that the object's speed is not constant but is changing over time. This implies the object is accelerating or decelerating.
Therefore, when the distance-time graph is a curved line, it signifies that the speed of the object is changing with time.
