OCR As Physics B Paper 2 2025 Question Paper

Download the official OCR AS Level Physics B H157/02 Physics in Depth question paper from the June 2025 examination series. This downloadable PDF contains the complete OCR AS Physics B Paper 2 exam sat on Wednesday 21 May 2025, including calculation problems, practical-investigation tasks, graph-analysis exercises, extended-response questions, and real-world Physics applications in the original OCR exam format.
The OCR H157/02 June 2025 question paper covers major AS Physics B topics including internal resistance, electromotive force, Newton’s second law, acceleration investigations, Young modulus, stress-strain graphs, free-fall experiments, systematic and random uncertainty, resistivity, specific thermal capacity, LDR circuits, potential dividers, graph interpretation, rocket propulsion, momentum, iterative modelling, and ion-thruster propulsion systems.

Section A focuses on experimental Physics and data analysis through practical investigations involving cells and internal resistance, Newton’s second law trolley experiments, Young modulus determination using copper wire, and free-fall timing using electromagnets and trap doors. Students are required to analyse graphs, perform calculations, explain systematic errors, interpret experimental data, and apply AO1 knowledge, AO2 application, and AO3 analytical reasoning to practical Physics scenarios.

Section B includes extended structured questions on resistor tolerances, resistivity and thermal energy calculations, nichrome-wire design, LDR potential-divider circuits, burglar-alarm systems, and graphical analysis of resistance against light intensity. Candidates must evaluate experimental methods, explain circuit behaviour, perform percentage and uncertainty calculations, and interpret real-world electronic applications.

Section C focuses on rocket propulsion and iterative computational modelling. Students are required to calculate exhaust-gas speed, analyse changing acceleration during fuel burn, complete iterative velocity calculations, evaluate modelling assumptions, and compare the suitability of conventional chemical rockets and ion thrusters for interstellar space missions using quantitative Physics reasoning.

This OCR AS Physics B Physics in Depth question paper is ideal for timed exam practice, practical-skills revision, modelling and graph-analysis training, and improving AO1 knowledge, AO2 application, and AO3 evaluation skills under authentic OCR examination conditions. Pair this paper with the official OCR H157/02 June 2025 mark scheme on markscheme.net for complete examiner-standard revision and self-assessment. Updated for the 2025/2026 academic year, fully mobile-friendly, and instantly downloadable.

This document is designed for AS Level Physics students preparing for the 2026 OCR examination series, resit candidates improving Physics in Depth exam performance, home-educated learners, and independent candidates studying OCR AS Physics B.
