Newton's Laws-1,2 or 3?
Every object in a state of motion tends to remain in that state of motion unless an external force is applied to it.
What is Newton's 1st Law
This property describes how air pushes on everything around it
What is air pressure
The force that moves an object forwards
What is thrust
Birds develop thrust by doing this with their wings
What is flapping
When thrust is greater than drag the object will go in this direction.
What is forward
When a ball is dropped and hits the ground then bounces up is an example of this law
What is Newton's 3rd law
Air can be weighed because it has this
What is mass
The force that attracts all objects to the ground
What is gravity
These 3 living things are able to fly
What are bats, birds, insects
These people were said to be the inventors of the first airplane
Who are the Wright brothers
Acceleration is produced when a force acts on a mass
What is Newton's 3rd law
This property describes how air fills the volume of a confined area
What is air takes up space
A force that slows down or prevents the forward motion of an object through air
What is drag
What is the ideal shape of a wing to achieve flight?
What is airfoil shape
The law of flight states that air particles always travel from......
What is high pressure to low pressure
A ball that keeps on rolling until it hits a wall is an example of this
What is Newton's 1st law
What is low air pressure
This force has to be greater than the force attracting objects to the ground in order to achieve flight
What is lift
A hot air balloon does this since it does not have wings to achieve flight.
What is floating/hover
explained: Hot air trapped in the balloon envelope allows the object to float through the cooler air surrounding it.
Hot air is lighter than colder air.
the amount of matter in an object or substance.
What is mass
As someone pedals their bike they will accelerate because of this
What is Newton's 2nd law
Air never stops doing is
What is pressing
This principle is what causes flight to occur
What is Bernoulli's Principle
Living and non-living things that attempt to fly will always have two forces working against them; those two forces are...
What is gravity and drag
What is the study of air in motion?
What is aerodynamics
