Fluids
Liquid or gas phases of matter
Fluid Mechanics
The study of fluid movement and forces
Pressure
The force pushing directly on a given surface
Pascal
Unit of pressure equal to one newton of force over a square meter
Pascal's principle
Changes in pressure in a confined fluid are distributed equally in all directions throughout the fluid
Hydraulic machines
Machines which use fluid to transmit or increase force
Archimedes' principle
The buoyant force exerted on a body in a fluid is equal to the weight of the fluid displaced
Bernoulli's principle
States that the pressure of a fluid decreases as its speed increases
Boyle's law
The volume of a dry gas is inversely proportional to the pressure it exerts, if the temperature remains constant
Barometer
A device used to measure atmospheric pressure
Charles's law
The volume of a gas at constant pressure is directly proportional to its Kelvin temperature
