pressure
equals the force exerted on a Surface divided by the total area over which is the force is exerted
Pascle
the unit of pressure
fluid
A material that can easily flow
the buoyant laws
Water and other fluids exerting in upward Force
Archimedes' Principle
The buoyant force acting on a submerged object is equal to the weight of the fluid the object displays
Density
a substance is mass per unit volume
Hydraulic action
uses liquid to transmit pressure and a confined liquid
Bernoulli's Principle
the faster a fluid moves the less pressure that fluid exerts
lift
an upward Force
