Question
- A. An object moving at constant speed — calculation focus for distance-time graph
- B. This confuses distance and displacement and does not answer Distance-time graphs.
- C. This is too vague because it does not use the force or motion quantity named in the objective.
- D. This reverses the physical cause and effect for Forces and motion.
Answer
The correct answer is: An object moving at constant speed — calculation focus for distance-time graph
Explanation
The correct option is An object moving at constant speed — calculation focus for distance-time graph. An object moving at constant speed — calculation focus for distance-time graph is correct because it matches the approved learning objective to interpret a straight sloping line on a distance-time graph as constant speed. This answer belongs to Distance-time graphs within Forces and motion, so it must use precise AQA GCSE Physics forces and motion vocabulary. The other options are wrong because they either confuse distance and displacement, omit the required force or motion condition, or move away from the exact subtopic being tested.
Common mistake
Misinterpreting Distance-Time Graphs
Students often think that a straight sloping line on a distance-time graph indicates an object is accelerating rather than moving at a constant speed.
Remind students that a straight sloping line represents constant speed, and emphasize the difference between constant speed and acceleration.
