What pressure means
Pressure tells you how concentrated a force is. The same force on a smaller area produces a larger pressure, which is why a sharp drawing pin goes in more easily than a flat thumb.
Step-by-step lessons covering OCR GCSE Physics Pressure 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.
