equal to the force exerted on a surface divided by the total area over which the force is exerted
pressure
unit of pressure
pascal
a material that can easily flow
fluid
an instrument that can measure atmospheric pressure
barometer
the ratio of the mass of a substance to its volume
density
an upward force that water and other fluids exert
buoyant force
states that the buoyant force acting on a submerged object is equal to the weight of the volume of fluid displaced by the object
Archimedes’ Principle
states that pressure increases by the same amount throughout an enclosed or confined fluid
Pascal’s Principle
uses liquids to transmit pressure and multiply force in a confined fluid
hydraulic system
states that the faster a fluid moves, the less pressure the fluid exerts
Bernoulli’s Principle
an upward force
