Fluids, Buoyancy, and Archimedes' Principle

Guided Notes

3 key concepts

  • 1

    A fluid is any substance that can flow and alter its shape because its particles can move around.

  • 2

    Archimedes' principle states that an object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid that is displaced.

  • 3

    A floating object displaces fluid based on its mass, while a sinking object displaces fluid based on its volume.
