What does a horizontal line on a distance-time graph represent?
Think about what happens to distance when time passes but the object doesn't move.
What does a steep slope indicate?
Recall how speed relates to the steepness of a graph.
What does the slope of a distance-time graph represent?
Remember how steepness relates to movement on the graph.
True or False: A horizontal line in a distance-time graph indicates that the object is accelerating.
Consider what happens to distance when there is no movement.
A distance-time graph indicates that an object traveled from point A to point B in 20 seconds at a steady speed, then back to A in 25 seconds. Analyze the graph and provide the total distance covered.
Break down the distance into two segments: A to B and B back to A.
An object travels at a different speed for each segment of the journey: it covers 40 meters in the first 10 seconds and then 60 meters in the next 15 seconds. Sketch the distance-time graph and identify its characteristics.
Determine slopes for both segments to capture the change in speed.
