Grade 6 Aerodynamics and Flight Unit Test

This force slows a plane down. It is caused by air friction.

• Lift

• Thrust

• Weight

• Drag

When an airplane is taking off, lift is _______ than weight.

• greater than

• less than

• the same as

This is an engine-powered force that pushes the plane forward through the air.

• thrust

• weight

• drag

• lift

This force is created when air rushes over the top of the wings and pushes up on the wings raising the plane skyward.

• weight

• thrust

• lift

• drag

A force that is always directed toward the center of the Earth.

• Gravity

• Thrust

• Lift

• Drag

This is the main body of a glider or a plane.

• engine

• wings

• aircraft

• fuselage

These provide lift for an aircraft. What are they?

• wings

• engines

• fuselages

• forces

What is the name of the force that tries to hold an aircraft back?

• thrust

• weight

• drag

• lift

Whose principle is used to describe why flight is possible?

• Newton

• Guidry

• Bernoulli

• Pascal

Bernoulli's Principle states....

• the air moves faster under the wing which generates lift

• the air moves faster over the wing which generates lift.

• you can only fly if your teacher says so

• Nothing
