Question
- A. Deformation that is not fully reversed when the force is removed — calculation focus for inelastic deformation
- B. This confuses elastic and plastic deformation and does not answer Stretching and deformation.
- 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: Deformation that is not fully reversed when the force is removed — calculation focus for inelastic deformation
Explanation
The correct option is Deformation that is not fully reversed when the force is removed — calculation focus for inelastic deformation. Deformation that is not fully reversed when the force is removed — calculation focus for inelastic deformation is correct because it matches the approved learning objective to define inelastic deformation as deformation that is not fully reversed when the force is removed. This answer belongs to Stretching and deformation 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 Inelastic Deformation
Students often confuse inelastic deformation with elastic deformation, thinking that all deformation is reversible.
Emphasize that inelastic deformation does not fully return to the original shape when the force is removed, unlike elastic deformation which does.
