Daniel Bernoulli, Sir Isaac Newton
What is Newton's first law?
every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force
rotation around the longitudal axis is called __________
roll
pure flight involves using a force to ___________ a machine _____________.

what is thrust?
artificial force, pushes or pulls an airplane forward
Who flew the 1st manned hot air balloons?

relative wind
21 November 1783 - ______minute balloon flight over ____________.
25, Paris
What is Newton's third law?
for every action there is an equal and opposite reaction
the rotation around the vertical axis is called __________
yaw
a natural force that pulls you down

increase, maintain
1299 AD - Marco Polo saw __________ sailors attached to kites being used as __________ observers. This could be considered the first manned aircraft.
Chinese, military
What is Bernoulli's principle?
As the velocity of a fluid increases, the pressure decreases
when the flaps are ____________ it __________ wing area
down, increases
what is lift
artificial force, creates pressure changes needed for lift
___________ ______________ goes through the plane front to back

___________ are used in takeoff and to increase drag
flaps
4 ways to increase lift
1. a greater surface area
2. increase the curve of the upper camber of the wing
3. increase speed
4. increase angle of attack (up to a certain point)
