Fluids and Pressure Flashcards
(10 cards)
What is a Fluid?
Any matter that can flow and that can take the shape of its container.
Give an example of a fluid.
Examples are-
-Waterfalls
-hot air ballons
-etc
What do ALL fluids do?
All fluids exert pressure.
What is pressure?
Pressure is force over a given area.
Give an example of pressure.
Examples are-
-Bike tires
-Basketball bouncing
-etc.`
What is a Pascal?
A Pascal is equal to 1 Newton over 1 squared m (meter I think)
What does kPA stand for?
kPA stands for Kilo-pascal or 1,000 Pa
What is the equation for pressure?
Pressure= Force/Area
What is Atmospheric Pressure?
The weight of gas atoms(oxygen, nitrogen, etc) that are being pulled by gravity.
Is there more pressure closer to the earth’s surface or higher in the atmosphere?
Earth’s surface has more pressure because gravity pulls the oxygen down and there are fewer particles of mass, pushing down the higher the atmosphere.
