PLTW Flight and Space

The force that directly opposes the weight of an aircraft and holds the aircraft in the air.

• Lift

• Thrust

• Drag

• Weight

You are designing an airplane to carry liquid cargo that will slosh and move side to side in its container. This could make the plane unstable. What type of airfoil would you use for the wing? Why?

• Low Camber

• High Camber-Thick wing section

• Symmetrical Camber

• High Camber-Thin wing section

This rocket launched but did not orbit.

Which statement most accurately describes what happened to this rocket?

• The thrust was greater than the weight.

• The thrust was so great that the rocket went into orbit.

• The thrust was less than the weight.

• The thrust was great enough for launch, but not enough for orbit.
