Forces in Fluids

TermDefinition
Fluid Any material that can flow and that takes the shape of its container (any liquid or gas).
Pressure The amount of force exerted on a given area.
Formula to calculate pressure Force/Area (force divided by area) =
Pascal The SI unit for pressure.
Atmospheric Pressure The Pressure caused by the weight of the atmosphere.
Buoyant Force The upward force that keeps an object immersed in or floating on a liquid.
Archimedes' Principle The principle that states that the buoyant force on an object in a fluid is an upward force equal to the weight of the volume of fluid that the object displaces.
Bernoulli's Principle The principle that states that the pressure in a fluid decreases as the fluid's velocity increases.
Lift An upward force on an object that moves in a fluid.
Thrust The pushing or pulling force exerted by the engine of an aircraft or rocket.
Drag A force parallel to the velocity of the flow; it opposes the direction of an aircraft and, in combination with thrust, determines the speed of the aircraft.
Pascal's Principle The principle that states that a fluid in equilibrium contained in a vessel exerts a pressure of equal intensity in all directions.
Thermal Expansion Matter expands when it is heated and contracts when it is cooled.
Archimedes’ Principle The buoyant force on an object in a fluid is equal to the weight of the fluid displaced by the object.
