Question
- A. Because energy is proportional to the square of the extension — definition focus for extension
- 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: Because energy is proportional to the square of the extension — definition focus for extension
Explanation
The correct option is Because energy is proportional to the square of the extension — definition focus for extension. Because energy is proportional to the square of the extension — definition focus for extension is correct because it matches the approved learning objective to identify extension in metres when using the elastic potential energy equation. 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
Common Mistake in Elastic Potential Energy Calculations
Students often confuse extension in the elastic potential energy equation, using incorrect units such as centimeters instead of meters.
Always convert extension to meters before substituting into the elastic potential energy equation.
