When you throw a paper plane in the air, you are giving the plane a push to move forward. That push is a type of force called_____________?

• Gravity

• Force

• Thrust

• Drag

Air moving over and under the wings is providing an upward __________ force on the plane.

• Drag

• Lift

• Gravity

• Thrust

air pushing back against the plane is slowing it down, creating a ________ force.

• Lift

• Thrust

• Gravity

• Drag

The weight of the paper plane also affects its flight, as _________ pulls it down toward Earth.

• Gravity

• Thrust

• Lift

• Drag
