QUE SIGNIFIE BUOYANT EN ANGLAIS
Flottabilité
En science, la flottabilité /bɔɪ.ənsi/ est une force ascendante exercée par un fluide qui s'oppose au poids d'un objet immergé. Dans une colonne de fluide, la pression augmente avec la profondeur en raison du poids du fluide sus-jacent. Ainsi, une colonne de fluide, ou un objet submergé dans le fluide, présente une plus grande pression au bas de la colonne que sur le dessus. Cette différence de pression entraîne une force nette qui tend à accélérer un objet vers le haut. La grandeur de cette force est proportionnelle à la différence de pression entre le haut et le bas de la colonne et équivaut également au poids du fluide qui occupe autrement la colonne, c'est-à-dire le fluide déplacé. Pour cette raison, un objet dont la densité est supérieure à celle du fluide dans lequel il est submergé a tendance à couler. Si l'objet est moins dense que le liquide ou est formé de manière appropriée, la force peut maintenir l'objet à flot. Cela peut se produire uniquement dans un cadre de référence qui a un champ gravitationnel ou qui accélère en raison d'une force autre que la gravité définissant un sens "vers le bas".
définition de buoyant dans le dictionnaire anglais
La première définition de flottabilité dans le dictionnaire est capable de flotter ou de s'élever à la surface d'un liquide. Une autre définition de flottabilité est capable de maintenir un corps à flot ou de le faire augmenter. La flottabilité est également gaie ou résiliente.
