Fluid Mechanics and Archimedes' Principle

Flashcards covering significant terms and concepts related to fluid mechanics and Archimedes' principle.

Archimedes' Principle

A principle stating that any object submerged in a fluid displaces a volume of liquid equal to its own volume.

Volume

A measure of how much space an object occupies.

Density

A measure of how much mass occupies a given volume. It indicates how tightly packed matter is.

Buoyancy

The net upward force that a fluid exerts on an object.

Atmospheric Pressure

The pressure exerted by the weight of the atmosphere, approximately 101 kPa at sea level.

Pressure

Force per unit area exerted on a surface, dependent on depth in a fluid.

Displacement Rule

A submerged object displaces a volume of liquid equal to its own volume.

Buoyant Force

The upward force that a fluid exerts on a submerged object, equal to the weight of the fluid displaced.

Fluid Dynamics

The branch of physics concerned with the movement of liquids and gases.

Hydrostatic Pressure

The pressure at a certain depth in a fluid, determined by the fluid's density and the depth.
