Pressure (Edexcel GCSE Physics): Quizzes

Force per unit area on a surface

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

Pascal (Pa), where 1 Pa = 1 N/m²

Collisions between particles and surfaces

Decreases pressure

More particles, leading to more collisions

Increases pressure by raising particle speed

It decreases

Increases steadily with depth

$P = h \times \rho \times g$

About 101,325 Pa or 101.3 kPa

Small force creates larger force via fluid
