Pressure (p = F ÷ A)
AQA GCSE Physics calculation · part of the free Calculation Climb
Pressure = force ÷ area, in pascals (Pa = N/m²). The same force over a smaller area makes a bigger pressure.
How to do it — step by step
- pressure = force ÷ area.
- p = F ÷ A. (Rearrange: force = pressure × area.)
Worked example
A 200 N force acts on 0.5 m².
p = 200 ÷ 0.5 = 400 Pa
