Question 1

Newtons First Law of Motion

Answer 1

Willingness of an object to stay at rest or continue in motion. Inertia

Question 2

Newtons 2nd law of Motion

Answer 2

acceleration of an object is dependent on the object and mass of the object

Question 3

Newtons 3rd law of motion

Answer 3

for every reaction there an opposite and equal reaction

Question 4

Bernoulli’s Principle

Answer 4

States that as the speed of a fluid increases the pressure decreases

Question 5

The Airfoil

Answer 5

Part of an aircraft that produces lift as it passes through the air. Consists of leading, trailing, chord line, and camber

Question 6

Airfoil of a fixed wing aircraft

Answer 6

wings

Question 7

airfoil of a helicopter

Answer 7

rotor blades

Question 8

Leading edge

Answer 8

front edge or surface of the airfoil

Question 9

trailing edge

Answer 9

the rear edge or surface of an airfoil

Question 10

chord line

Answer 10

an imaginary straight line from the leading edge to the trailing edge

Question 11

Camber

Answer 11

the curve or departure from the chord line. from its leading to trailing edge of the airfoil

Question 12

Relative Wind

Answer 12

the direction of the airstream in relation to the airfoil

Question 13

Angle of Attack

Answer 13

the angle between the chord line and the relative wind

Question 14

Lift is accomplished by

Answer 14

the difference in the airflow across the airfoil

Question 15

Lift

Answer 15

force that acts in an upward direction.

Must be greater than or equal to weight for sustained flight

Question 16

weight

Answer 16

force of gravity acting downward on the aircraft

Question 17

thrust

Answer 17

acts in the forward direction.

must be greater than or equal to drag for flight to begin or sustained

Question 18

Drag

Answer 18

holds an aircraft back

caused by the disruption of the airflow on the aircraft.

Question 19

Longitudinal Axis

Answer 19

associated with roll, bank, turn.

axis runs fore and aft through the length of the aircraft

Question 20

Lateral axis

Answer 20

associated with pitch.

pitch axis runs from the left to the right of the aircraft

Question 21

Vertical Axis

Answer 21

associated with yaw.

axis runs from the top to the bottom of the aircraft.

Question 22

fixed wing aircraft depends on what motion for lift

Answer 22

forward motion
