(10 cards)
Buoyancy
Tendency of an object in a fluid to rise or sink due to density differences with its surroundings.
Density
Amount of mass contained in a given volume
Flow rate
Measure of the speed at which a fluid flows from one point to another, determined by measuring the amount of fluid that flows past a given point in a given time.
Pressure
Amount of force applied to a given area
Compressibility
Property of being able to be compressed or made more compact
Viscosity
Resistance of a fluid to flow
Displacement
Occurs when something takes the place of something else
Pascals law
Law that states that when force is applied to an enclosed fluid, the increase in pressure is transmitted equally to all parts of the fluid
Buoyant force
Is the upward force that a fluid exerts on an object
Archimedes Principle
Archimedes Principle states the upward, buoyant, force that is exerted on a body immersed in a fluid is equal to the weight of the fluid displaced by the object.
