Physics of Flight Center of Gravity
Flying Machines
The center of gravity will determine if your
plane will dive, stall, or glide straight.
Position a paper clip along your fuselage to
experiment.
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
Flying Machines
The Center of Gravity is the point at which an
object balances. How can you find the center of
gravity?
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.
