The ==Key Stage 3=====Meaning===[[Pressure]] is the [[force]] on a surface per unit [[area]]. ===About Pressure===: [[Pressure]] is [[measure]]d in [[Pascal]]s ([[Pa]]).: A large [[force]] on a small [[area]] causes a large [[pressure]].: A small [[force]] on a large [[area]] causes a small [[pressure]]. ===Equation===: Pressure = Force/Area:<math>P = F \divide A</math>
