Buoyancy
Buoyancy
•
Buoyancy is an upward
force that fluids exert on an object
Finding
Buoyancy Force
•
This force is equal to
the weight of the fluid displaced (moved out of the way) by the object
Buoyancy
and Floating
•
An object will float
when the weight of the displaced fluid is greater than or equal to the weight
of the object.
Example
Problem
•
One ml of water has a
mass of one gram.
•
If an object has a mass
of 15 grams and displaces 17 milliliters of water, will it float?
Answer
•
The weight of the water
is greater than the mass of the object.
•
Therefore, the object
will float.
