SUMMARY
The forum discussion centers on the differences between Archimedes' principle and Atwood's principle in the context of buoyancy and acceleration. A sphere with a volume of 0.4 m³ and a mass of 100 kg experiences a buoyant force of 4000 N according to Archimedes' principle, resulting in an acceleration of 40 m/s². In contrast, the Atwood principle suggests a buoyant force of approximately 1600 N, leading to an acceleration of 16 m/s². The discussion highlights confusion surrounding the definitions of "buoyancy force" and "dynamic buoyancy force," and critiques the validity of the Atwood principle as presented in a Wikipedia article.
