3 cards from this section. Quick, good the night before a test.
What is Archimedes' Principle?
Think about the relationship between weight and fluid displacement.
Define buoyant force.
What force acts in opposition to gravity when in fluid?
What does Archimedes' Principle state?
Think about how weight relates to displacement.
True or False: An object floats when the buoyant force is greater than its weight.
Remember the balance of forces for flotation.
A solid object of mass 200 g is submerged in water. Calculate the buoyant force if the object displaces 150 cm³ of water.
Use the weight of the displaced water for calculations.
An object has a density of 800 kg/m³ and is submerged in water (density of 1000 kg/m³). Will it float or sink, and why?
Relate the densities to buoyant force.
