Model answer
What a good answer should say
- Model Limit response 29ebd6: state Distinguish elastic deformation from plastic deformation., apply resultant vector, momentum conservation, impulse, Hooke law, stress, and finish with the physical consequence for Materials.
Explanation
Why this works
Stem being answered: Explain Distinguish Elastic Deformation From Plastic Deformation in a way that directly answers the AQA A-Level Physics objective. Route focus: mechanics-and-materials / Materials.
Key vocabulary for this item: distinguish, elastic, deformation, plastic. Written check: state the principle, apply it to the named context, and close with the requested conclusion.
The explanation should keep the answer tied to these exact words rather than a general physics summary, using units, graph evidence or equation reasoning only when they are relevant to the stem.
