Understand this objective

Short explanation

In the subtopic Pressure on a surface (physics only), this learning objective focuses on (Physics only) Define pressure as force per unit area. 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) Define pressure as force per unit area. 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.
