composition of air
what is an experiment you can do to prove air has oxygen.
light a candle and then put a jar over it. the candle will burn out because the oxygen is gone
what is one method of propulsion in a plane
what is a get engine
prove how air takes up space
if you put Plasticine over a jar with a funnel over top and try to pour water in you cant because air takes up space.
what is aerodynamics
what is the science of moving through air
what does fast and slow air equal
fast air equals low pressure and slow air equals high pressure
what are the rough percentages of carbon dioxide oxygen and argon.
78% carbon dioxide, 21% oxygen and 1% argon.
what is another method of propulsion
what is a propeller
prove how air can be compressed
if you put your thumb on then end on the syringe it will get hard to push as the air is being compressed
what is combustion
what is a rapid form of oxidization
what is an experiment to prove Bernoulli's principle
put two spoons together over a sink and they will click together
what is an experiment to prove air contains carbon dioxide.
when lime water touches air it becomes foggy because there is corbon dioxide in the air
how do birds generate propulsion
flapping there wings
prove how air exerts pressure
if a bottle with a balloon on top is in hot water the balloon will expand because air exerts pressure
what is compression
what is the squeezing of partials
explain what Bernoulli's principle is
how lift occurs
Name one type of oxidization
what is combustion
what muscle do birds use to flap there wings.
what is a pectoral
prove how air has mass
if two ballons are on a string and one is filled up the one that is filled will be heavier
what is a propeller
a curved object that spins
what is newtons third law
every action has an equal and opposite reaction
name a different type of oxidization
what is rust
what shape is an airfoil
an object shape for air to move around it
prove how temperature affects air
if the air is hot it will expand and if it is cold they will compress.
what is a glider
an aircraft that flies without an engine
does the faster the air move the lower the air pressure
yes
