Homework

What are the 4 forces of flight and how do they make a plane fly?:
The forces are lift, thrust, gravity, and drag. Lift lifts up the plane and makes it go up, thrust forces the plane forward, gravity brings the plane down, and drag slows the plane down.

Your Definition of flight:
I think that flight is when the air in some way helps the object go in the air, by lifting it or thrusting it, not just barging through the air.
