Real-Life Communication -- Solution
Here are the answers:
1. What are the four aerodynamic forces that help planes fly?
They are lift, weight, thrust and drag.
2. How is lift created?
The slower moving air underneath the wing is pushing up harder than the faster moving air over the top of the wing.
3. What creates the force of weight?
It is created by gravity pulling down on the airplane.
4. How much lift is necessary to make an airplane stay up?
It must equal the weight of the airplane.
5. What is thrust?
It is the force that moves the aircraft forward.
6. What is drag?
It is the force that slows an aircraft down.
7. How much thrust is necessary for an airplane to fly?
It must equal drag in order for a plane to fly.
