Neutral Buoyancy

Neutral buoyancy is a condition in which a physical body's density is equal to the density of the fluid in which it is immersed. This offsets the force of gravity that would otherwise cause the object to sink. An object that has neutral buoyancy will neither sink nor rise.

In scuba diving, the ability to maintain neutral buoyancy through controlled breathing is an important skill.

Famous quotes containing the words neutral and/or buoyancy:

    The lonely Earth amid the balls
    That hurry through the eternal halls,
    A makeweight flying to the void,
    Supplemental asteroid,
    Or compensatory spark,
    Shoots across the neutral Dark.
    Ralph Waldo Emerson (1803–1882)

    She keeps
    The Topic over intellectual deeps
    In buoyancy afloat. They see no ghost.
    With sparkling surface-eyes we ply the ball:
    It is in truth a most contagious game:
    Hiding the Skeleton, shall be its name.
    George Meredith (1828–1909)
