Faire un schéma pour illustrer la poussée d'Archimède dans un cours : première étape, un objet accroché à un dynamomètre avec poids de 4 Newton au dessus d'un récipient plein d'eau contenant un bec verseur. La 2e étape, Le même objet est plongé dans le récipient à ce moment-là le poids ne fait plus que 1 Newton. L'eau est déversée sur le côté dans un pot sur une balance. On peut lire le poids de 3 Newton Ver más
