Questions

Here are the questions:

1) What are the four forces of flight and how do they make a plane fly?
The four forces of flight are lift, drag, thrust, and gravity (or weight). Lift keeps a plane up in the air for a certain amount of time. Gravity pulls the plane or flying device towards the earth. Thrust propels the plane forward and also helps create more of a lift. Drag makes the plane slow down but it also helps the plane change direction.
2) Your definition of flight.
My definition of flight is what makes the plane stay in the air for a certain amount of time. It also makes sure the plane can move through the air. Basically flight is whatever makes the flying device stay in the air or stay airborne.
