Buoyancy-cool science experiment
This video shows how the melting of ice changes the buoyancy force on the ice cube. Ice cube melting reduces their buoyancy and gravity is dominated force until a drop of water drops from the cube. At this point the lift force is greater than the weight of the cube. The process is repeated ...
Videoposnetek pokaže, kako se s taljenjem ledu spreminja sila vzgona na kocko ledu. Taljenje kocke ima za posledico zmanjševanje vzgona in prevladuje sila teže, vse dokler se kapljica vode ne odlepi od kocke. Takrat je sila vzgona večja od teže kocke. Proces se ponavlja...
