A

Forces in motion

17
Q

Gravity

A

The natural force pulling everything to earth

18
Q

Leading edge

A

The front part of a wing or airfoil

19
Q

Lift

A

The upward force that opposes gravity and supports the weight of an aircraft

20
Q

Relative wind

A

The flow of air which moves opposite the flight path of an airplane

Q

Thrust

A

The force which moves an aircraft forward in flight

22
Q

Upwash

A

The upward movement of air ahead of the wing in flight

23
Q

Vortex

A

A spinning column of air that is created behind the wingtip as a result of air moving from an area of high pressure on the bottom to an area of low pressure on top

Q

Wind

A

Air in motion
