Short explanation

In the subtopic Pressure on a surface (physics only), this learning objective focuses on (Physics only) Explain why a smaller area gives a greater pressure for the same force. For AQA GCSE Physics 8463 Unit 4.5 Forces, keep the explanation inside Pressure on a surface (physics only) and Pressure and pressure differences in fluids (physics only). Approved keywords for this objective include pressure, force, area, and physics only. A strong answer separates force and pressure, uses correct units where quantities are involved, and links the physical reasoning back to (Physics only) Explain why a smaller area gives a greater pressure for the same force. This is not a generic revision point: it is specifically about Pressure on a surface (physics only), Pressure and pressure differences in fluids (physics only), and the approved wording of the learning objective.
