Theme A · Space, time and motion
Work, energy and power examines energy transfers, conservation, efficiency and the rate of doing work.
Observed assessment
Based on the exam material analysed in our dataset.
Based on 2024–2025 HL exam material analysed in our private dataset. Reviewed 2024 items are included only where mapped to the current syllabus. These observations describe the analysed sample and are not predictions of future examinations.
Question demands
Preparation focus
The observed assessment mix for Work, Energy and Power is strongly weighted toward applying physical ideas and carrying out calculations. Students should be comfortable identifying relevant energy transfers, selecting appropriate relationships and connecting work, power and efficiency to physical situations. The analysed sample for this topic is smaller than for A.1 and A.2, so the distribution should be treated as descriptive rather than predictive.
