Question 1

The inertia of a body is determined by it’s _______ thus

changes in altitude (do/do not) affect inertia.

Answer 1

Mass/ Do Not

Question 2

When a helicopter climbs at increasing airspeed, its inertia (does/does not) change. But it’s momentum (increases/ decreases/ remains constant)

Answer 2

Does not/ Increases

Question 3

When the mass of air through a rotor system becomes less, the downward acceleration must be (greater/smaller) to provide the same opposing force to weight

Answer 3

greater

Question 4

When a helicopter is in a steady state turn at a constant airspeed, the aircraft (is/is not) accelerating because it is constantly changing

Answer 4

is/ direction

Question 5

The strength of an arm is (increased/ decreased) when the lever arm is increased

Answer 5

increases

Question 6

Kinetic energy ( doubles/ quadrupoles) when airspeed is doubled

Answer 6

quadrupoles
