Forces influence the motion and properties of fluids.
(c) McGraw Hill Ryerson 2007
Forces
FORCE•Anything that causes a change in the motion of an object.
•A push or pull.
(c) McGraw Hill Ryerson 2007
Balanced and Unbalanced Forces
BALANCED FORCES ARE...•Equal in strength•Opposite in direction•No movement
(c) McGraw Hill Ryerson 2007
Balanced and Unbalanced Forces
UNBALANCED FORCES ARE...•Unequal in strength
•Cause a change in speed or direction
(c) McGraw Hill Ryerson 2007

Buoyancy
BUOYANCY•The upward force on an object submerged in or floating on fluids.
•The Diver has neutral buoyancy.
(c) McGraw Hill Ryerson 2007
Buoyancy
The amount of buoyant force that would push up against the object immersed in the fluid equals the force of gravity or the weight of the fluid that the object displaces.
(c) McGraw Hill Ryerson 2007
Buoyancy (Archimedes Principle)

Buoyancy
DENSITY& BUOYANCYIf the density of the immersed object is greater than the density of the fluid, it will SINK
(c) McGraw Hill Ryerson 2007
Buoyancy
AVERAGE DENSITYThe total mass of all substances that make up an object divided by the total volume.
