Short explanation

In the subtopic Pressure in liquids (physics only), this learning objective focuses on (Physics only) Describe upthrust as the upward force on an object in a fluid. For AQA GCSE Physics 8463 Unit 4.5 Forces, keep the explanation inside Pressure in liquids (physics only) and Pressure and pressure differences in fluids (physics only). Approved keywords for this objective include upthrust 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) Describe upthrust as the upward force on an object in a fluid. This is not a generic revision point: it is specifically about Pressure in liquids (physics only), Pressure and pressure differences in fluids (physics only), and the approved wording of the learning objective.
