Conceptual Physics Test with Correct Answers

Conceptual Physics Test with Correct Answers Distinguish between force and pressure - Answer-Pressure is force/area What is the relationship between liquid pressure and depth of a liquid? Between liquid lressure and density? - Answer-Liquid pressure increases with depth; it increases with density Why does the buoyant force act upward for an object submerged in water? - AnswerThere is greater pressure against the bottom How does the buoyant force that acts on a fish compare with the weighht of the fish? - Answer-Same How does the volume of a competely submerged object compare with the volume of water displaced? - Answer-Same When the buoyant force on a submerged object is more than the weight of the object, how do the densities of the object and water compare? - Answer-Object's density is less Does the buoyant force on a floating object depend on the weight of the object itself or on the weight of the fluid displaced by the object? Or are these both the same for the special case of floating? - Answer-Both are the same What causes atmospheric pressure? - Answer-The weight of air
