Learning Objective
I can predict and explain how changes in mass and shape affect an object's buoyancy.
- 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.
