Condition experienced while in free-fall, in which the effect of gravity is cancelled by the inertial (e.g. centrifugal) force resulting from orbital flight. 7, record 2, English, - weightlessness

In an orbiting spacecraft, zero gravity is experienced as weightlessness. 7, record 2, English, - weightlessness
Record number: 2, 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 2, English, - weightlessness

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 2, 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 2, Spanish, - ingravidez

Acceleration in a direction opposite to the velocity, or in the direction of the negative axis of a coordinate system. 2, record 3, English, - negative%20acceleration
Record number: 3, Textual support number: 1 OBS
A negative acceleration does not always mean the object is slowing down. If an object were moving in the negative direction, the acceleration would be negative as the object gained speed and positive when the object lost speed. An example of this is the acceleration due to gravity. An object in free fall has a negative acceleration even though it is increasing speed. It is negative because the object is moving in a negative direction. 3, record 3, English, - negative%20acceleration

The Free Fall Machine(FFM) is an apparatus that provides simulated microgravity for long duration experiments. The system is based on the principle of free fall. The free fall periods in the FFM is at maximum around 900 ms and is interrupted by a acceleration of about 20 g for about 20-80 ms. 2, record 5, English, - accelerated%20free%20fall%20machine
