Archimedes Principle
What is the upward force in this principle called?
Buoyant force.
Do all fluids exert pressure?
Yes.
Give three examples of fluids.
Air, water, blood, ect...
Do all fluids flow the same?
No
Who was Archimedes?
A Greek mathematician.
What is the SI unit abbreviation for Pascal?
Pa
If the fluid's speed increases, what will happen to the pressure?
It will decrease.
What is viscosity?
The resistance of a liquid to flow.
What did Archimedes discover?
A method for determining buoyancy.
How is Pascal's Principle stated?
p1=p2
If you have a wide and a narrow section of pipe, where will the water flow the fastest?
The narrow section of pipe.
What is buoyant force?
The upward force that fluids exert on matter.
What is the upward force equal to?
The weight of the volume of fluid displaced.
What is a device that uses liquid to transmit pressure called?
A hydraulic device.
What is the formula for pressure?
force/area
What is a fluid with a greater viscosity than water?
Honey, syrup, ect...
What is Archimedes Principle?
The buoyant on an object in a fluid is an upward force equal to the weight of the volume of fluid that the object displaces.
What is Pascal's principle?
A change in pressure at any point in an enclosed fluid will be transmitted equally to all parts of the fluid.
What is Bernoulli's Principle?
As the speed of a moving fluid increases, the pressure of the moving fluid decreases.
What is a fluid?
A non solid state of matter in which the molecules are free to move past each other.
