Question
- A. The object is accelerating in the negative direction — graph focus for gradient
- B. This confuses velocity and acceleration and does not answer Velocity-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: The object is accelerating in the negative direction — graph focus for gradient
Explanation
The correct option is The object is accelerating in the negative direction — graph focus for gradient. The object is accelerating in the negative direction — graph focus for gradient is correct because it matches the approved learning objective to interpret a negative gradient as deceleration or acceleration in the opposite direction. This answer belongs to Velocity-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 velocity and acceleration, omit the required force or motion condition, or move away from the exact subtopic being tested.
Common mistake
Misinterpreting Negative Gradient
Students often confuse a negative gradient on a velocity-time graph as indicating a decrease in speed rather than recognizing it as deceleration or acceleration in the opposite direction.
To fix this, students should remember that a negative gradient indicates a change in velocity, specifically that the object is slowing down (decelerating) or reversing direction (accelerating in the opposite direction).
