Read each question carefully and answer to the best of your ability. Show your work where applicable.
1. Which type of graph best represents an object that is moving at a constant speed?
Distance-time graph with a curved line
Speed-time graph with a diagonal line
Distance-time graph with a straight, diagonal line
Speed-time graph with a horizontal line at zero
2. A speed-time graph with a horizontal line above the x-axis indicates acceleration.
3. The slope of a distance-time graph represents the object's .
4. When an object is at rest, its distance-time graph will be a line.
5. Describe the motion of an object represented by a speed-time graph that shows a line starting at zero speed and gradually increasing.
6. A steeper line on a distance-time graph indicates a slower speed.
True
False
7. Consider a distance-time graph where the line is horizontal. What does this tell you about the object's speed?
8. Draw a simple distance-time graph that represents an object moving at a constant speed, then stopping for a period, and finally returning to its starting position at a constant speed.
