Pascal
State pascal's principle
when a change in pressure is applied to an enclosed fluid, it is transmitted undiminished to all portions of the fluid and to the walls of its container
Archimedes Principle - State it
when a body is partially or completely immersed in a fluid, it experiences an apparent loss in weight that is equal to the weight of the fluid displaced by the immersed part of the body(s)
Bernoulli's principle
What is as the speed of a fluid increases, the pressure within the fluid decreases?
the amount of force exerted per area
Pressure
The pressure of an object is equal to
force/area
Unit for pressure
Pascals
Nationality of Archemedes
Greek
speed decreases so pressure
increases
What is a substance that has no fixed shape, and takes the place of its container
fluid
1 kilopascal = __________ pascals
1000
What does fluid pressure depend on?
Depth and type
bathtub
the method with which Archimedes came up with his principle
The curve on a car's spoiler faces
downward
What is the ability or tendency to float in water or air or some other fluid?
buoyancy
Density of water
1g/ml or 1g/cm3
What does not matter when experiencing fluid pressure?
fluid under the subject
The buoyant force on an object equals the _______ of the water displaced by the object
weight
Pressure inside a tornado
low
What is a machine that uses pressure in a fluid to accomplish a task?
Hydraulic
Density equation
Density = m/V
the reason a fish is able to stay in one spot in the water and not sink or float
neutral buoyancy
When an object floats on the surface of a fluid it does not ______ its entire volume.
displace
The speed of the air above the wing is ________ creating ___________ pressure
