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.
