Review Questions

• How did Archimedes' work with buoyancy impact the understanding of fluid mechanics?
  • Archimedes' discovery of the principle of buoyancy revolutionized the understanding of fluid mechanics. He established that an object submerged in a fluid experiences an upward force equal to the weight of the fluid it displaces. This insight allowed for better comprehension of why objects float or sink and laid the groundwork for advancements in hydrostatics and engineering applications in subsequent eras.
