The topic contains 4 subtopics, 22 topic questions and 22 marks in total. Rows count only the parts tagged to that subtopic, keep the same colour in both charts and repeat paper count, tagged marks and year range in the native table. ## Topic question count and mark distribution Subtopics are on the vertical axis and sorted from highest to lowest. Only the parts whose knowledge graph matches a subtopic are counted for it, and percentages are each row's share of the tagged total in that chart. A part tagged to several subtopics is counted in each bar, so the bars are not a partition of the topic total. ### Questions by subtopic question items - [4 recall and use $E_P = \frac{1}{2}Fx = \frac{1}{2}kx^2$ for a material deformed within its limit of proportionality](https://www.examsci.com/topics/cie-ial/physics/9702-paper-1/elastic-and-plastic-behaviour/4-recall-and-use-e-p-frac-1-2-fx-frac-1-2-kx-2-for-a-material-deformed-within-its/) (10 papers) — 12 · 41.4% - [1 understand and use the terms elastic deformation, plastic deformation and elastic limit](https://www.examsci.com/topics/cie-ial/physics/9702-paper-1/elastic-and-plastic-behaviour/1-understand-and-use-the-terms-elastic-deformation-plastic-deformation-and-elastic/) (6 papers) — 6 · 20.7% - [3 determine the elastic potential energy of a material deformed within its limit of proportionality from the area under the force–extension graph](https://www.examsci.com/topics/cie-ial/physics/9702-paper-1/elastic-and-plastic-behaviour/3-determine-the-elastic-potential-energy-of-a-material-deformed-within-its-limit-of/) (6 papers) — 6 · 20.7% - [2 understand that the area under the force–extension graph represents the work done](https://www.examsci.com/topics/cie-ial/physics/9702-paper-1/elastic-and-plastic-behaviour/2-understand-that-the-area-under-the-force-extension-graph-represents-the-work-done/) (5 papers) — 5 · 17.2% ### Marks by subtopic marks - [4 recall and use $E_P = \frac{1}{2}Fx = \frac{1}{2}kx^2$ for a material deformed within its limit of proportionality](https://www.examsci.com/topics/cie-ial/physics/9702-paper-1/elastic-and-plastic-behaviour/4-recall-and-use-e-p-frac-1-2-fx-frac-1-2-kx-2-for-a-material-deformed-within-its/) (10 papers) — 12 · 41.4% - [1 understand and use the terms elastic deformation, plastic deformation and elastic limit](https://www.examsci.com/topics/cie-ial/physics/9702-paper-1/elastic-and-plastic-behaviour/1-understand-and-use-the-terms-elastic-deformation-plastic-deformation-and-elastic/) (6 papers) — 6 · 20.7% - [3 determine the elastic potential energy of a material deformed within its limit of proportionality from the area under the force–extension graph](https://www.examsci.com/topics/cie-ial/physics/9702-paper-1/elastic-and-plastic-behaviour/3-determine-the-elastic-potential-energy-of-a-material-deformed-within-its-limit-of/) (6 papers) — 6 · 20.7% - [2 understand that the area under the force–extension graph represents the work done](https://www.examsci.com/topics/cie-ial/physics/9702-paper-1/elastic-and-plastic-behaviour/2-understand-that-the-area-under-the-force-extension-graph-represents-the-work-done/) (5 papers) — 5 · 17.2% ## Subtopic comparison matrix Curriculum order is by syllabus number, then alphabetically.

They are ordered by syllabus number, then alphabetically, and each row opens a page of matching past-paper questions. **How are the subtopic question and mark totals calculated?** A multiple-choice question contributes one item and its marks to every subtopic it is tagged with. A structured question contributes one item per tagged part, and that part’s marks; untagged parts of the same question are not counted here. A part tagged to several subtopics therefore appears under each of them. **Why do some subtopics have no numbered prefix?** Practical-skills statements and some syllabus bullets are unnumbered. Numbered statements come first; unnumbered statements and ties are sorted alphabetically. **Is the LaTeX rendered without JavaScript?** Yes. Subtopics that contain formulas are converted to static KaTeX HTML during the build, and the KaTeX stylesheet is served from the same site. --- Full page with native tables, bar charts and Practice Hub links: https://www.examsci.com/topics/cie-ial/physics/9702-paper-1/elastic-and-plastic-behaviour/
