What is inertia
|
The willingness of an object to remain at rest or in motion unless acted upon by an outsude force.
|
|
What is acceleration
|
The rate of change in speed and/or velocity of matter with time.
|
|
What is speed
|
Te rate of movement in a given amount of time.
|
|
What is velocity
|
The quickness or speed of an object in a given time and direction.
|
|
What is Newton's first law
|
(Inertia) An object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an outside force.
|
|
What is Newton's second law
|
(Force) If an object moving in uniform speed is acted upon by an external force the change of motion will be directly prpoportional to the amount of force and inversly proportional to the mass of the object being moved.
|
|
What is Newton's third law
|
(Action and reaction) For every action there is an equal and opposite reaction.
|
|
Define Bernioulli's Principle
|
When a fluid is moving through a tube that reaches a constriction or narrowing the speed will increase and the pressure will decrease.
|

|
What is lift
|
The force that acts in an upward direction.
|
|
What is weight
|
The force of gravuty acting downward.
|
|
What is drag
|
The force that holds an aircraft back.
|
|

|
|
What are the primary flight controls for rotary wing
|
Collective stick, cyclic stick, foot pedals
|
|
What is the purpose of the flap
|
Increases lift
|
|
What is the purpose of the spoiler
|
Decreases lift
|
|
What is the purpose of speed brakes
|
They keep the speed from building too high during dives and prior to landing.
|
|
What is the purpose of the slats
|
Allows the aircraft to be controlled at speeds below the normal landing speed.
|
|
What is the angle of attack
|
The angle at which the air flow meets the fuselage
|
|
What is autorotation
|
A method of allowing a heo to land safely without engine power.
|
|

|
What are the effects of icing on aircraft
|
Ice on the airframe decreases lift and increases drag, weight, and stalling speed.
|
|
What is a bomb
|
Any weapon other than a torpedo, mine, rocket or missile dropped from the aircraft
|
|
What is a rocket
|
A weapon containing an explosive section and a propulsion section.
