Each topic below opens every past-paper question tagged to its syllabus points. - 9702 P1 - 12 papers - 480 topic questions - 480 marks - Syllabus 2025–2027 - [Browse 9702 P1 papers](https://www.examsci.com/past-papers/cie-ial/physics/9702-paper-1/) - [All paper codes](https://www.examsci.com/topics/) Core finding **Equations of motion leads 9702 P1 with 43 topic questions and 43 marks across 12 papers.** Kirchhoff’s laws follows with 30 topic questions and 30 marks. The current 2025–2027 dataset covers 32 topics, 480 topic questions and 480 marks. Each MCQ or structured part counts as one item, and each topic counts only the parts tagged to it, so the ranking reflects exam exposure rather than the number of question stems. Rows also carry paper count, mark total and year range for cross-unit comparison. The native table reproduces every figure in curriculum order. ## Topic question count and mark distribution Topics are on the vertical axis and sorted from highest to lowest. Only the parts whose knowledge graph matches a topic are counted for that topic, and percentages are each row's share of the tagged total in that chart. A part tagged to several topics is counted in each bar, so the bars are not a partition of the unit total. ### Questions by topic question items - [Equations of motion](https://www.examsci.com/topics/cie-ial/physics/9702-paper-1/equations-of-motion/) (12 papers) — 43 · 7.6% -

edge cases **Where can I find 9702 P1 topic questions?** This page groups every 9702 P1 topic question by topic and syllabus point. Open a topic to see the question numbers, marks and the session each one comes from, then follow the link into the original paper. **How many topics are in the current 9702 P1 syllabus?** This page lists 32 topics tagged to the current syllabus across 12 9702 P1 papers (2025–2026). Topics are ordered by syllabus number, then alphabetically. **How are question counts and marks calculated?** Each MCQ counts as one question item and each structured part counts as one item. Marks come from the official part marks. Only parts whose knowledge graph matches a topic are counted, and a part tagged to more than one topic is counted against each topic, so topic rows describe exam exposure rather than a partition of the paper. **Why is there no topic chart on the D1 index?** The D1 index intentionally stops at the paper-code level. Topic names are only shown after a code is selected, which prevents two units from claiming the same topic phrase or URL. **Which sessions are included?** All sessions tagged to the current syllabus are included, covering 2025–2026. Questions without a recognised syllabus tag are treated as current so they do not disappear from the index. --- Full page with native tables, bar charts and Practice Hub links: https://www.examsci.com/topics/cie-ial/physics/9702-paper-1/
