Which of the following is an example of "Air takes up space":

• blowing up the ballloon makes the balloon expand

• an empty baloon weighs less than a blown up balloon

Elevators control

• the pitch motion of the craft. Pitch means going up or down.

• the lift of the plane

• allows plane to land safely

• the yaw motion or the side to side motion of the plane

Rudders control ...

• the lift of the plane

• allows the plane to land safely

• the yaw motion is the side to side movement of the nose of the craft

The wing on the airplane controls...

• the lift of the plane.

• the thrust

• helps control pitch
