What is Buoyancy?
|
Ability of a fluid to exert an upward force on an object immersed in the fluid
|
|
|
What is Density?
|
mass per unit volume of material. (denisty of water is 1kg/1liter=1) D=m/v
|
|
|
What is Volume?
|
amount of space occupied by an object
|
|
|
What is Weight?
|
GRAVAITATIONAL FORCE exerted on an object by earth. (mass x gravity) F=ma
|
|
|
What is Pressure?
|
pressure is the force per unit area applied to the surface of an object. (Pa=F/A)
|
|
|
Explain Archimedes Principle
|
The buoyant force on an object equals the weight of the fluid displaced by the object
|
|
|
Explain Pascal's Principle
|
the pressure applied at any point, to a confined fluid is transmitted equally throughout the fluid
|
|
|
Explain Bernoulli's Principle
|
When the velocity of a fluid increases, the pressure exerted by the fluid decreases
|
|

|
|
What is Pressures Units
