### Fluids: Statics

• Density is the mass per unit volume: Density = Mass/Volume.
• If a force F acts on a surface of area A, the pressure P on the surface is P = F/A.
• The pressure in a fluid at a depth h is P = P at the surface + (fluid density)gh.
• If an object is placed in a fluid, such as water, the fluid exerts an upward force on the object; this force is known as the buoyant force.
• Archimedes principle: The buoyant force acting on an object in a fluid is equal to the weight of fluid displaced by the object.
