Only the parts whose knowledge graph matches this syllabus statement are counted, and the table shows which parts of each question are involved. - 28 topic questions - 19 papers - 98 tagged marks - 40.6% of topic questions - 40.5% of topic marks - 2020–2025 - Syllabus 2020–2027 - [All 9709 P4 Momentum topic questions](https://www.examsci.com/topics/cie-ial/mathematics/9709-p4/momentum/) - [All paper codes](https://www.examsci.com/topics/) Core finding **This Momentum syllabus point appears in 19 9709 P4 papers across 2020–2025, contributing 28 topic questions and 98 marks.** The most recent appearance is 9709/41 October/November 2025. That equals 40.6% of the 69 topic questions and 40.5% of the 242 marks tagged to Momentum. Only parts tagged to this subtopic are counted, so a four-part question can contribute one item and one part's marks. The table lists every matching question, its tagged parts and marks, with a link back to the paper page. Sessions are newest first, so the statement can be traced back through the full paper history. ## Topic questions by session Newest sessions first. Parts and marks count only the parts tagged to this subtopic; “x of y parts” shows how much of the question is tagged elsewhere.

Other parts of the same questions are assessed under different statements and are excluded from this page. **Which papers include this subtopic?** The table lists every matching session from 2020–2025. Each row links to the question anchor on the paper page, where the full paper context and practice entry point are available. **Why can one question appear under several subtopics?** The parts of one question can assess different syllabus statements. Each part is counted under its own subtopics, so the same question stem can appear on several subtopic pages while each page lists only the parts and marks tagged to that statement. **Can I practise these questions with AI marking?** Yes. Open a paper from the table and use the Interactive Practice Hub entry point. The page itself is static HTML so search engines and retrieval agents can read the full question list without executing JavaScript. --- Full page with native tables, bar charts and Practice Hub links: https://www.examsci.com/topics/cie-ial/mathematics/9709-p4/momentum/use-conservation-of-linear-momentum-to-solve-problems-that-may-be-modelled-as-the/
