the scientic process
what is a hypoythesis
an explanation why something happens
air takes up this
space
when air moves is creates areas of blank pressure and blank pressure
high and low
force acting upward
lift
define procedure
tthe steps taken to do something
air has this
mass
air travels faster over the top, creating lift
fporce acting downward
gravity
name 3 variables
controlled, responding, amnipulated
air is affected by this
temperature
define low pressure
particles spread out farther
force acting backward
drag
what are inferences
conclusion you draw based on the evidence
air is also affected bt this
altitude
define high pressure
particles more closely packed
force acting forward
thrust
what are materials
the things you need to conduct an experiment
air is a blank and can be blank
fluid, compressed
why is the bottom of a wing flat
it creates high pressure
for a plane to fly, the force acting blank must be greater than the force acting blank
upward, downward
