🎯 Exam Focus — AQA Physics
Frequency: This topic appears in approximately 4 out of 5 recent AQA sittings (HIGH). Pressure calculations and explanations are extremely common.
Typical Question Types:
- "Calculate the pressure exerted by..." — P = F/A calculation (2-3 marks)
- "Explain why a sharp knife cuts more easily than a blunt one" (3-4 marks) — must use P = F/A reasoning
- "Explain why pressure in a liquid increases with depth" (2-3 marks)
- "Why does atmospheric pressure decrease with altitude?" (2 marks)
- "Explain what is meant by upthrust" (2 marks — Higher)
- P = hρg calculations (Higher Tier, 3 marks)
What Examiners Look For:
- For "explain why sharp knife" questions: must name both area being smaller AND pressure being greater, and link using P = F/A
- For fluid pressure questions: must state "acts in all directions" not just downward
- For atmospheric pressure: "less air above" is the key phrase — depth argument but for air not water
- Always state units in calculations: Pa not just a number
