Question
- A. 0.25 m — misconception focus for extension
- 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: 0.25 m — misconception focus for extension
Explanation
The correct option is 0.25 m — misconception focus for extension. 0.25 m — misconception focus for extension is correct because it matches the approved learning objective to calculate extension by subtracting original length from stretched length. 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 Extension Calculation
Students often forget to convert the original length and stretched length into the same units before subtracting to find the extension.
Always ensure that both lengths are in the same unit (e.g., both in meters) before performing the subtraction to calculate the extension.
