What the hydrostatic balance is implying is that the vertical motion upwards is equal to the downward motion of gravity. In other words there is a net zero motion in the vertical direction.  3, record 1, English, - hydrostatic%20balance

Record number: 1, Textual support number: 2 CONT

Air does not rush off into space because the upward-directed pressure gradient force is nearly always balanced by the downward force of gravity. When these two forces are in exact balance, the air is said to be in hydrostatic equilibrium.  2, record 1, English, - hydrostatic%20balance

On appelle équilibre hydrostatique l'équilibre entre la composante verticale de la force du gradient de pression et la force d'attraction due à la gravité. L'atmosphère est habituellement en équilibre hydrostatique sauf, par exemple, dans le cas du mouvement vertical associé aux orages et dans lequel l'air est accéléré vers le haut ou le bas.  2, record 1, French, - %C3%A9quilibre%20hydrostatique

In the zero-energy universe hypothesis, the total amount of energy in the universe is exactly zero. The conventional zero-energy universe hypothesis is based on quantum fluctuation and the exact cancellation of positive-energy matter by negative-energy gravity through pseudo-tensor... or the inflation... before the Big Bang.  1, record 2, English, - zero%2Denergy%20universe%20hypothesis

In an orbiting spacecraft, zero gravity is experienced as weightlessness.  7, record 3, English, - weightlessness

Record number: 3, Textual support number: 1 OBS

A condition of apparent absence of an acceleration field. This may be experienced during unopposed acceleration at that rate imposed by the gravitational field (e.g. free fall in a vacuum or within a closed vessel), when the gravitational force is countered by an equal and opposite force (as in orbital flight) or during flight at escape velocity. Partial simulation is commonly conducted by immersion in a liquid of specific gravity close to that of the body.  6, record 3, English, - weightlessness

État d'un corps tel que l'ensemble des forces gravitationnelles et inertielles auxquelles il est soumis possède une résultante et un moment résultant nuls.  7, record 3, French, - impesanteur

Record number: 3, Textual support number: 1 CONT

L'impesanteur, dans le domaine de l'astronautique comme dans tout autre, est l'état d'un corps tel que l'ensemble des forces gravitationnelles et inertielles auxquelles il est soumis possède une résultante et un moment résultant nuls. L'impesanteur [...] est donc le phénomène ressenti en l'absence de pesanteur. L'impesanteur n'est donc pas provoquée par l'éloignement de la Terre ou de tout autre corps céleste attractif : l'accélération due à la gravité à une hauteur de 100 km par exemple n'est que de 4 % moindre qu'à la surface de la Terre. En réalité, l'impesanteur est ressentie lorsque l'accélération subie égale la gravité, ce qui recouvre aussi le cas où le champ de gravité serait nul, ce qui n'arrive pas puisque l'influence de la gravité est partout dans l'Univers.  8, record 3, French, - impesanteur

Se define ingravidez como el estado en el que un cuerpo tiene peso nulo. El motivo por el cual el peso se hace nulo es que la fuerza gravitatoria sea contrarrestada por la fuerza centrífuga (en un sistema de referencia solidario con el cuerpo) o por alguna fuerza de igual intensidad que el peso, pero que actúe en la dirección opuesta.  1, record 3, Spanish, - ingravidez

... two scientists at Imperial College, London, have perfected a system by which a flame in a spacecraft can be safely used for cutting, welding and even cooking. The genius of their discovery is that, until now, it has been difficult to keep a flame burning in zero gravity.... Prof. Felix Weinberg and Dr Fred Carleton have built a simple machine called an "electro-gas dynamic chimney", which creates the effect of a draught that enables the flame to keep burning.  1, record 6, English, - electro%2Dgas%20dynamic%20chimney
