pressure
the result of a force distributed over an area
pascal
the SI unit of pressure
fluid
a substance that assumes the shape of its container
hydraulic system
a device that uses pressurized fluid acting on pistons of different sizes to change a force
lift
upward force on an object
buoyancy
The ability of a fluid to exert an upward force on an object placed in it
buoyant force
upward force exerted on an object immersed in a fluid
Archimedes principle
the buoyant force on an object is equal to the weight of the fluid displaced by the object
