Advanced Activities: Forces in Flight

1.	The flight of an airplane, a bird, or any other object involves four forces: lift, drag, thrust, and weight. (Check the correct answer.)
	True False

2.	The direction assigned to the weight is downward. (Check the correct answer.)
	True False

3.	Any force pushing an airplane (or bird) forward is called ________. (Check the correct answer.)
	drag weight thrust

4.	_________ is generated by the engines of the airplane (or by the flapping of the bird's wings). (Check the correct answer.)
	Drag Weight Thrust

5.	The four types of drag are friction drag, form drag, induced drag, and stall drag. (Check the correct answer.)
	True False

6.	The friction drag is the friction force at the surfaces of the plane caused by the heat of the engine. (Check the correct answer.)
	True False

7.	The form drag, or pressure drag, is directly related to the shape of the body of the airplane. (Check the correct answer.)
	True False

8.	Any object that moves through a fluid can get an increase in form drag by streamlining. (Check the correct answer.)
	True False

9.	Aircraft designers try to design wings that lower induced drag. (Check the correct answer.)
	True False

10.	_________ drag generally only happens when the airplane is flying faster than the speed of sound. (Check the correct answer.)
	induced form wave
