Physics of Flight - C1L2

Upward force on aircraft against weight

• thrust

• drag

• lift

• indifference

Lift can be created by

• greenhouse gasses

• more speed - increase aircraft’s forward motion

• reducing power

• extending flaps and landing gear

Angle of attack

• the angle between the oncoming air and the wing

• The angle between the pilot's nose and forehead

• The angle between the ground and the airplane

• the angle of the throttle to the propeller

Increasing the angle of attack (pull back on stick/yoke) will

• Induce panic with passengers

• pitch the airplane nose down

• increase lift - up to the point of a stall anyway

• improve fuel efficiency

Angle of attack and velocity (speed) must be __________ to keep flight path level

• disproportionate

• agreeable

• balanced

• congruent

Air conditions effecting the need for greater or lesser velocity to maintain lift

• Temperature

• Humidity

• Both 1 & 2 (blue & green) are correct

• none of the above

Weight

• increases lift

• is a measure of distance and relativity

• is a gravitational force on an object due to its having mass

• I think I need to loose a little

Adding more parts, fuel, passengers and freight mean more

• vectored thrust

• water buoyancy

• Bernellian lift

• total mass (weight)

The more mass, the more ....

• the more, the merrier

• resistance to moving

• the more sassafras

• the more cushion

a forward force that moves an aircraft through the air

• drag

• lift

• thrust

• anger
