Force, Area & Pressure

Drag the sliders to feel P = F ÷ A: the same force on a smaller contact area means more pressure. The depth slider shows fluid pressure, P = ρgh.

Surface pressure  P = F ÷ A
20.00 kPa
20,000 Pa
Applied force200 N
Contact area100 cm²
Fluid pressure  P = ρgh

Depth in water10.0 m
Fluid: water · density ρ = 1000 kg/m³ · g = 9.81 m/s²
Tip: shrink the contact area and watch the gauge climb — halving the area doubles the pressure.
