Question
- A. The spring constant is 200 N m⁻¹ — calculation focus for elastic potential energy
- B. This confuses elastic and plastic deformation and does not answer Elastic potential energy.
- 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 spring constant is 200 N m⁻¹ — calculation focus for elastic potential energy
Explanation
The correct option is The spring constant is 200 N m⁻¹ — calculation focus for elastic potential energy. The spring constant is 200 N m⁻¹ — calculation focus for elastic potential energy is correct because it matches the approved learning objective to distinguish force-extension calculations from elastic potential energy calculations. This answer belongs to Elastic potential energy 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
Confusing Calculations
Students often confuse force-extension calculations with elastic potential energy calculations, leading to incorrect results.
To fix this, clearly identify whether you are calculating force using Hooke's law (F = k * e) or elastic potential energy (Ee = 0.5 * k * e^2) and ensure you use the correct formula for each scenario.
