Pressure Calculations - AQA GCSE Physics Practice Book

Pressure comes in two forms at GCSE: solid surface pressure and fluid pressure. Students need to pick the right formula and apply it correctly. This AQA GCSE Triple Physics workbook covers both with 12 scaffolded questions using the EVERY method framework.

The EVERY method breaks each calculation into clear steps: Equation, Values, Enter values into the equation, Rearrange if needed, Your units. Every question has a structured EVERY table for students to complete, building a consistent problem-solving habit. Questions get progressively harder: Q1-3 are straightforward, Q4-6 introduce unit conversions, and Q7-12 require rearranging the formula.

What’s inside:

• 12 progressive questions on Pressure (p = F/A and p = h x rho x g)
• Structured EVERY method table on every question page
• Progressive difficulty: simple substitution, then unit conversions, then rearranging
• Self-assessment tracker with “What made me stuck?” reflection checklist
• Full worked answers for all 12 questions using the EVERY method steps

AQA specification reference: 6.5 Forces (Triple Physics only)

Pressure calculations require students to use p = F/A for solid surfaces (e.g. a person standing on snow) and p = h x rho x g for fluid columns (e.g. water pressure at depth). Students convert between Pa, kPa, and atmospheres.

Common student mistakes this workbook addresses: using area in cm2 instead of m2, confusing depth with total height of the container, forgetting to use density in kg/m3 (not g/cm3), and mixing up the two pressure formulae.

Suitable for AQA GCSE Physics (Triple only). Works for both foundation and higher tier students.
