At a garden party, a person wearing stiletto heels steps onto the grass and immediately sinks in. Their friend in snowshoes strolls across without leaving a mark. Both people weigh exactly the same. The difference? Pressure. It's not just about how hard you push — it's about how much area you spread that force across. A stiletto heel concentrates all your weight onto roughly 1 cm² of ground. A snowshoe spreads it over 2000 cm². Same force, tiny area = enormous pressure. That's the whole idea.
This introduction covers The Stiletto That Sank Into the Lawn within Pressure for GCSE Physics. Revise Pressure in Forces for GCSE Physics with 15 exam-style questions and 12 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 1 of 16 in this topic. Use this introduction to connect the idea to the wider topic before moving on to questions and flashcards.

What is pressure?
The force acting per unit area on a surface.
P = F / A
What is the equation for pressure?
P = F / A
Pressure (Pa) = Force (N) ÷ Area (m²)
