Archimedes' Principle
Why submarine can dive in the water, floating, or even hover? This is mainly related to gravity and buoyancy, according to "float of the Law" (or Archimedes' principle), any object in the liquid are subjected to the action of buoyancy, buoyancy equal to the size of the object itself displaces weight of the liquid when the weight of the object is larger than the buoyancy it will sink;. will go up less than buoyancy; equal will hover in the liquid buoyancy, these two forces are equal in magnitude, but the direction is opposite.
