What is density? | Density is the ratio of mass to volume |
What is buoyancy? | The tendency of an object in a fluid to rise or sink due to density differences with its surroundings |
What is Archimedes principle? | The buoyant force on an abject is equal to the weight of the fluid displaced by the object |
What is pressure? | The amount of force applied to a given area |
