Match each graph feature to what it shows
Draw a line connecting each graph description on the left to its correct meaning on the right. Or write the matching letter next to each description.
| Graph feature | Your answer | What it means |
|---|---|---|
| Steep upward slope | A. Returning toward the starting point | |
| Horizontal flat line | B. Moving away from start at slow speed | |
| Gentle upward slope | C. Moving away from start at fast speed | |
| Downward slope | D. Stationary — not moving | |
| Curved line (getting steeper) | E. Speeding up (accelerating) |
True or False? Fix the false ones
Circle T or F for each statement. If the statement is false, rewrite it correctly on the line below.
A steeper gradient on a distance-time graph means the object is moving slower.
Correct it:
A horizontal line on a distance-time graph means the object is moving at constant speed.
Correct it:
The gradient (slope) of a distance-time graph equals the object's speed.
Correct it:
A downward slope on a distance-time graph means the object is slowing down.
Correct it:
1. A student says "the highest point on a distance-time graph is where the object is moving fastest." Is this correct? Explain your answer.
2. Describe the shape of a distance-time graph for a student who walks quickly to the canteen, stops for 3 minutes to buy lunch, then walks slowly back to class.
