Revise AQA GCSE Physics 5.5 Pressure and pressure differences in fluids with the question bank and revision guides.
A fluid can be either a liquid or a gas. The pressure in fluids causes a force normal (at right angles) to any surface. • The pressure at the surface of a fluid can be calculated using the equation: pressure = force normal to a surface / area of that surface, p = F/A. pressure, p, in pascals, Pa; force, F, in newtons, N; area, A, in metres squared, m².
