enFIRoad Block: Forces in Fluids9
pressure: the force applied to a unit area of surface
pascal:a unit of pressure equal to one newton per square meter
fluid:a continuous amorphous substance that tends to flow and to conform to the outline of its container, a liquid or a gas
Pascal: Principle that states when force is applied to a confined fluid, the change in pressure, is transmitted equally to all parts of the fluid
hydraulic system:a mechanism operated by the resistance offered or the pressure transmitted when a liquid is forced through a small opening or tube
lift:an upward force
Bernoulli: Principle that states as the velocity of a fluid increases, the pressure exerted by the fluid decreases
buoyancy:the ability of a liquid or a gas to exert an upward force on an object that is immersed in it
buoyant force:the upward force that keeps an object immersed in or floating on a fluid
Archimedes:Principle that states the buoyant force on an object is equal to the weight of the fluid displaced by the object
