On the buoyancy formula of water I've always been confused with F = g and Archimedes principle Take this question for example The submarine begins to dive from the sea until it is completely submerged. In this process, how does the buoyancy of the sea change If f is used in this problem, the buoyancy force should be constant In Archimedes' words, row V becomes larger and row f becomes larger How to judge I'm crazy about buoyancy

F = g
The v-row becomes larger and the f-float becomes larger
There's nothing wrong with it,
When the object is still floating on the liquid, f = g = the weight of the liquid discharged
When the submarine begins to dive from the sea until it is completely submerged, its buoyancy increases slowly
The reason why the submarine still sank to the sea level is that the sea water continuously poured into the boat, making the submarine sink, and the G object also kept growing, so there was no contradiction
