Short explanation

In the subtopic Atmospheric pressure (physics only), this learning objective focuses on (Physics only) Explain that the atmosphere becomes less dense at greater height. 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 atmosphere 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 that the atmosphere becomes less dense at greater height. 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.

Misunderstanding Atmospheric Density: Emphasize that as height increases, there is less air above to exert pressure, leading to lower density, and relate this to the concept of atmospheric pressure.
