Pressure in Fluids | GCSE Physics Practice
Pressure in a fluid (liquid or gas) increases with the depth of the fluid and its density.
Why does pressure increase as you go deeper in water?
What is Pressure in Fluids | Practice?
"The force exerted by a fluid per unit area."
The pressure in a liquid ____ as depth increases.
Calculate the pressure at a depth of 2m in water (density = 1000 kg/m³, g = 9.8 N/kg).
Why do dams have much thicker walls at the bottom than the top?
Fluid Pressure Facts
Pressure = force normal to a surface / area of that surface.
Pressure in a column = height x density x gravitational field strength.
Fluids exert pressure in all directions.
An object submerged in a fluid experiences upthrust.
Exam Fact: Upthrust is equal to the weight of the fluid displaced by the object.
