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 Densitys units
What is Pressures Units
