Exam-style question
Try this first
A velocity-time graph shows a horizontal line at 5 m/s for 10 seconds. What does this tell you about the object's motion during this time?.
Model answer
What a good answer should say
- The horizontal line at 5 m/s indicates that the object is moving at a constant velocity of 5 m/s for the entire 10 seconds.
Explanation
Why this works
The evidence of a horizontal line on a velocity-time graph indicates that there is no change in velocity over the time interval. This means the object is not accelerating or decelerating.
The implication is that the object maintains a steady speed, leading to the conclusion that it travels a consistent distance during this period.
