Short explanation
In the subtopic Atmospheric pressure (physics only), this learning objective focuses on (Physics only) Describe atmospheric pressure as pressure caused by air particles colliding with surfaces. For AQA GCSE Physics 8463 Unit 4.5 Forces, keep the explanation inside Atmospheric pressure (physics only) and Pressure and pressure differences in fluids (physics only). Approved keywords for this objective include atmospheric pressure, air particles, 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 atmospheric pressure as pressure caused by air particles colliding with surfaces. This is not a generic revision point: it is specifically about Atmospheric pressure (physics only), Pressure and pressure differences in fluids (physics only), and the approved wording of the learning objective.
