Question
- A. The object is stationary
- B. The object is moving at constant speed
- C. The object is accelerating
- D. The object is moving backwards
Answer
The object is moving at constant speed
Explanation
A straight line with a positive slope on a distance-time graph indicates that the object is moving at a constant speed.
Common mistake
Curved Distance-Time Graphs
Students often misinterpret a curved distance-time graph as constant speed instead of changing speed.
To fix this, students should remember that a curve indicates that the speed is not constant and is changing over time. They can practice by analyzing different curves and describing how the speed changes.
