What are the FOUR FORCES that act on an airplane as it flies?
Find out at this site.

LIFT

DRAG

So HOW does a plane fly?
How does such a heavy aircrafy even get off the ground?
Believe it or not, these FOUR FORCES are what allow for a plane to fly.
Visit NASA's OBSERVATORIUM and find out how the forces act on a plane to allow the plane to fly.  Please stop and do the experiments they suggest.  Record your thoughts about the experiments in your science journal.
 

So, how does the upward force of LIFT balance out the downwatd force of GRAVITY?
It the force of gravity is stronger, what will happen?
If the force of lift is too strong, what do you think would happen?
This site will give you information to help you answer this question.
