Flying Machines
The Problem
1) Almost everyone dreams of visiting exotic places. But traveling can waste a lot of time.
2) It takes waaaaaaay to long to get to school.
The Mission
Build-It-Yourself.com
Our mission is to build flying machines that get us from A to B fast.
Build a flying machine that could get us to school in 1 minute.

Physics of Flight – Center of Gravity
Build-It-Yourself.com
The center of gravity will determine if your plane will dive, stall, or glide straight. Position a paper clip along your fuselage to experiment.
Flying Machines
Dive:Paper clip too far
forward
Stall:Paper clip too far
to the rear
Glide:Paper clip at the Center of Gravity
Physics of Flight – Center of Gravity
Build-It-Yourself.com
The Center of Gravity is the point at which an object balances. How can you find the center of gravity?
Flying Machines
Center of Gravity
1)
2)
3)
Put two fingers at the ends of an object.
Gradually move your fingers toward each other keeping the object balanced.
When your fingers touch each other and the object is still balanced, that is the CENTER OF GRAVITY.
