Stores, transfers, and conservation
A system is the object or group of objects you decide to study. Physicists track energy using stores such as kinetic, gravitational, elastic, thermal, and chemical.
Step-by-step lessons covering OCR GCSE Physics Work done for Foundation and Higher tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 (Foundation Tier) or Paper 3 and Paper 4 (Higher Tier) format. Paper 2 and Paper 4 include synoptic questions that draw on Topics P1–P4, so revisit earlier topics before final exams rather than treating each paper as self-contained.
