Understand this objective

Short explanation

In the subtopic Atmospheric pressure (physics only), this learning objective focuses on (Physics only) Link atmospheric pressure to the weight of air above a surface. 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 and physics only. A strong answer separates mass and weight, uses correct units where quantities are involved, and links the physical reasoning back to (Physics only) Link atmospheric pressure to the weight of air above a surface. 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.
