Upward force on the submerged object (Archimedes)

Displaced fluid mass0.499

Buoyant force: 4.894 N

  • The object displaces 0.4990 kg of fluid.
  • That displaced mass weighs 4.894 N, which is exactly the upward push on the object.
  • This is Archimedes' principle: the buoyant force equals the weight of the fluid displaced.

Next stepIf the buoyant force exceeds the object's weight, it floats. Switch to Float/Sink mode to check.
