Air Pressure Flashcards
Mass
The amount of stuff in an object
Weight
The pull of gravity on an object
A type of force
Air Pressure
The weight of air pushing on all surfaces in all directions equally
Pressure
The force applied over an area
Gravity
The force that pulls two masses together
Newton’s gravitational constant
Force=F G=Gravitational Constant m=masses
r=distance between masses
Newtons
The metric unit for force
Air Pressure Measurement Units
Kilopascal, Millibar, Dynes, Inches in Mercury, Millimeters of Mercury, Pounds per Square Inch
Suction
When an imbalance of air pressure occurs so high pressure pushes on low pressure
Vacuum
A space with little to no matter and little to no air pressure like space
How does the cup experiment work
The low air pressure inside is being pushed in by the high air pressure outside (suction)
Heat vs Cold
When you heat up the particles they move faster therefore increasing air pressure, slowing them down does the opposite
What happens to air pressure as it (altitude) goes higher?
It lowers because there is less of a concentration (ears pop, you get sick, etc.)
True or false weight is a type of force?
True
Hypothesis
An explanation of a scientific occurence
