Chapter 3 Section 2 Buoyancy and Density
Density Review Density = mass(g) volume(cm3)The density of water is 1 g/cm3 A less dense object floats on a more dense object. The same is true for liquids.
Density Practice A piece of wood has a mass of 10g and a volume of 20 cm3. Will it float in water? A ball has a mass of 50g and a volume of 25 cm3. Will the ball float in water?
Buoyancy All liquids and gases exert a buoyant force on matter.Gravity exerts a force downward. The buoyant force exerts an upward force.
Floating In order to float the buoyant force must be greater than the force from gravity. Gravity is a pulling force. Buoyancy is a pushing force.
Archimedes’ PrincipleThe buoyant force is equal to the weight of the fluid displaced by an object. Example: A object displaces 50 N of water the buoyant force will be 50 N
Floating/Sinking If an object weighs 50N and displaces 50N of water, it will float. If an object weighs 150N and displaces 100N of water, it will sink.
Practice An object has a mass of 250g and displaces 200g of water. Does it float? An object has a mass of 50g and displaces 70g of water. Does it float?

Buoyancy & Archimedes’s Principle
The tendency or ability of an object to float.
DENSITY & BUOYANCY. BUOYANCY BUOYANCY = the ability to float in a fluid. Examples of fluids = water, air BUOYANT FORCE = the upward force that acts on.

BUOYANCY ARCHIMEDES’ PRINCIPLE. less density float Objects with less density will float on fluids with greater density. more densitysink Objects with.
Bernoulli’s, Pascal’s, & Archimedes’ Principles Principles of Fluids.
PHYSICS 103: Lecture 18 Archimedes Principle Example Problems Agenda for Today:
Density and Buoyancy. Float? Whether an object will float or not is dependent on the density of the object and the density of the fluid.
Floating and Sinking. Density is a measure of how closely packed the atoms in a substance are Density is a physical property All matter has measurable.
