Question
- A. The length of the spring when no force is applied — misconception focus for spring
- 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: The length of the spring when no force is applied — misconception focus for spring
Explanation
The correct option is The length of the spring when no force is applied — misconception focus for spring. The length of the spring when no force is applied — misconception focus for spring is correct because it matches the approved learning objective to describe how to measure the original length of a spring before adding loads. 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
Measuring Spring Length
Students often forget to measure the original length of the spring without any loads, leading to incorrect extension calculations.
Always ensure to measure the original length of the spring before adding any loads to accurately calculate the extension.
