La masse m<\/em> d’un corps, exprim\u00e9e en kilogramme, repr\u00e9sente la quantit\u00e9 de mati\u00e8re qui compose ce corps. Il ne faut pas confondre la masse d’un corps avec son poids. Ce dernier est la force de gravitation avec laquelle la Terre attire le corps. Le poids ets donc une force qui s’exprime en newton.<\/p>\n

Le poids d’un corps est proportionnelle au produit de sa masse m<\/em> et de l’acc\u00e9l\u00e9ration de la gravitation g<\/em>\u00a0 :<\/p>\n

\"P=mg\"<\/div>\n

Sur Terre, l’acc\u00e9l\u00e9ration de la gravitation est d’environs 9,81 m\/s2<\/sup>.<\/p>\n
