Forces
force that pulls the plane towards the ground
Gravity
Shape that gives wings their lift
airfoil
What is is called when the nose of the plane goes up or down
PITCH
A lighter plane requires less thrust to move than a heavier plane (which Newton's Law is this, and what does it say?)
Newton's Second Law... Force = Mass x Acceleration (Inertia)
force that opposes gravity
lift
shape of the wing from above or below
planform (NOT "planeform"!!)
What is it called when the wings of the plane go up or down (one up and one down)
ROLL
Which Newton's Law says that the plane will sit still until the motor turns the propeller (and what does it say)?
Newton's First Law - an object at rest will remain at rest until acted upon by an outside force.
force that gives the plane forward momentum
Thrust
general shape of the plane so as to move through the air easily
streamlines (or aerodynamic)
What is it called when the nose of the plane goes right or left?
YAW
The Law that helps planes take off
Newton's Third Law - for every action there is an equal and opposite reaction.
Force that opposes and slows the plane down
Drag
a glider has a HIGH one, a fighter jet has a LOW one
Aspect Ratio
This motion is controlled by the ELEVATORS
Pitch
What is the angle of the wings (particularly on takeoff) that uses Newton's 3rd Law?
Angle of Attack
Bernoulli
ratio of these two measurements - gives an indication of what KIND of wing this will be (glider - general - fighter jet, etc.)
Aspect Ratio - compares the AREA of the wing to the WINGSPAN
In a "coordinated turn" both of these control surfaces need to be activated so that the plane turns smoothly in both pitch and roll
RUDDER and AILEVONS
Why do the Voyager Spacecraft just keep going? They have both left the solar system!
No outside forces.. Newton's Third Law
