Pressure & Pressure Differences in Fluids (AQA GCSE Physics): Flashcards

Force spread over an area

At right angles (perpendicular)

$P = \frac{F}{A}$

Pressure in pascals (Pa)

Force in newtons (N)

Area in square metres ($\text{m}^2$)

Pascal (Pa)

$1 \text{ Pa} = 1 \text{ N/m}^2$

About 100,000 Pa (or 100 kPa)

Higher pressure (for same area)

Higher pressure (for same force)

Smaller area creates higher pressure
