The topic contains 5 subtopics, 198 topic questions and 668 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 - [• use the definition of power as the rate at which a force does work, and use the relationship between power, force and velocity for a force acting in the direction of motion](https://www.examsci.com/topics/cie-ial/mathematics/9709-p4/energy-work-and-power/use-the-definition-of-power-as-the-rate-at-which-a-force-does-work-and-use-the/) (18 papers) — 33 · 27.0% - [• understand the concepts of gravitational potential energy and kinetic energy, and use appropriate formulae](https://www.examsci.com/topics/cie-ial/mathematics/9709-p4/energy-work-and-power/understand-the-concepts-of-gravitational-potential-energy-and-kinetic-energy-and-use/) (19 papers) — 31 · 25.4% - [• understand and use the relationship between the change in energy of a system and the work done by the external forces, and use in appropriate cases the principle of conservation of energy](https://www.examsci.com/topics/cie-ial/mathematics/9709-p4/energy-work-and-power/understand-and-use-the-relationship-between-the-change-in-energy-of-a-system-and-the/) (19 papers) — 30 · 24.6% - [• solve problems involving, for example, the instantaneous acceleration of a car moving on a hill against a resistance](https://www.examsci.com/topics/cie-ial/mathematics/9709-p4/energy-work-and-power/solve-problems-involving-for-example-the-instantaneous-acceleration-of-a-car-moving/) (10 papers) — 15 · 12.3% - [• understand the concept of the work done by a force, and calculate the work done by a constant force when its point of application undergoes a displacement not necessarily parallel to the force](https://www.examsci.com/topics/cie-ial/mathematics/9709-p4/energy-work-and-power/understand-the-concept-of-the-work-done-by-a-force-and-calculate-the-work-done-by-a/) (12 papers) — 13 · 10.7% ### Marks by subtopic marks - [• understand and use the relationship between the change in energy of a system and the work done by the external forces, and use in appropriate cases the principle of conservation of energy](https://www.examsci.com/topics/cie-ial/mathematics/9709-p4/energy-work-and-power/understand-and-use-the-relationship-between-the-change-in-energy-of-a-system-and-the/) (19 papers) — 109 · 27.8% - [• understand the concepts of gravitational potential energy and kinetic energy, and use appropriate formulae](https://www.examsci.com/topics/cie-ial/mathematics/9709-p4/energy-work-and-power/understand-the-concepts-of-gravitational-potential-energy-and-kinetic-energy-and-use/) (19 papers) — 108 · 27.6% - [• use the definition of power as the rate at which a force does work, and use the relationship between power, force and velocity for a force acting in the direction of motion](https://www.examsci.com/topics/cie-ial/mathematics/9709-p4/energy-work-and-power/use-the-definition-of-power-as-the-rate-at-which-a-force-does-work-and-use-the/) (18 papers) — 95 · 24.2% - [• solve problems involving, for example, the instantaneous acceleration of a car moving on a hill against a resistance](https://www.examsci.com/topics/cie-ial/mathematics/9709-p4/energy-work-and-power/solve-problems-involving-for-example-the-instantaneous-acceleration-of-a-car-moving/) (10 papers) — 43 · 11.0% - [• understand the concept of the work done by a force, and calculate the work done by a constant force when its point of application undergoes a displacement not necessarily parallel to the force](https://www.examsci.com/topics/cie-ial/mathematics/9709-p4/energy-work-and-power/understand-the-concept-of-the-work-done-by-a-force-and-calculate-the-work-done-by-a/) (12 papers) — 37 · 9.4% ## 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/mathematics/9709-p4/energy-work-and-power/
