Question
- A. To ensure accuracy and reliability of results — calculation focus for graph
- B. This confuses elastic and plastic deformation and does not answer Required practical: force and extension.
- 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 elasticity.
Answer
The correct answer is: To ensure accuracy and reliability of results — calculation focus for graph
Explanation
The correct option is To ensure accuracy and reliability of results — calculation focus for graph. To ensure accuracy and reliability of results — calculation focus for graph is correct because it matches the approved learning objective to apply WS and MS skills when drawing graphs, finding gradients and evaluating repeatability. This answer belongs to Required practical: force and extension within Forces and elasticity, so it must use precise AQA GCSE Physics forces and motion vocabulary. The other options are wrong because they either confuse elastic and plastic deformation, omit the required force or motion condition, or move away from the exact subtopic being tested.
Common mistake
Common Mistake in Graphing
Students often misinterpret the gradient of a force-extension graph, thinking it represents the total force rather than the spring constant.
Remind students that the gradient of the linear section of a force-extension graph indicates the spring constant, not the total force applied.
