Question
- A. It becomes permanently deformed — application focus for F = ke
- B. This confuses elastic and plastic deformation and does not answer Hooke's law and spring constant.
- 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: It becomes permanently deformed — application focus for F = ke
Explanation
The correct option is It becomes permanently deformed — application focus for F = ke. It becomes permanently deformed — application focus for F = ke is correct because it matches the approved learning objective to apply MS 3b, MS 3c and MS 4a skills when using or graphing F = ke. This answer belongs to Hooke's law and spring constant 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
Misunderstanding Hooke's Law
Students often confuse the relationship in Hooke's Law, thinking that force and extension are not directly proportional beyond the limit of proportionality.
To fix this, students should practice identifying the limit of proportionality on force-extension graphs and understand that Hooke's Law applies only within this limit.
