💪 The Stiletto That Sank Into the Lawn
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.

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)
