Buoyant Force and Related Concepts

This set of flashcards covers key concepts related to buoyant force, including definitions, principles, and devices used to measure density.

Buoyant Force

The upward force exerted by a fluid on an object that is fully or partially immersed in it.

Archimedes' Principle

The buoyant force acting on an object is equal to the weight of the fluid displaced by that object.

Factors Influencing Buoyant Force

The density of the fluid and the volume of the object are the primary factors that influence the buoyant force.

Principle of Floatation

When an object floats in a fluid, the weight of the object is equal to the weight of the fluid displaced.

Hydrometer

A device used to measure the relative density of liquids.

Lactometer

A device used to measure the relative density of milk; it is a type of hydrometer.

Relative Density

The ratio of the density of a substance to the density of water.
