styrofoam glider from the front, fold the tab to the right so that it
resembles the diagram on the Rudder - Yaw Web page.What motion do you

glider. Was the motion the same as your prediction in the question above?
varies If not, describe how
it differed. varies.

should have yawed counterclockwise around its center of gravity if viewed
from the front. Where is its center of gravity in terms of the length
of the airplane? varies
- Now bend the tab
left. Predict the motion you will see when you fly the styrofoam glider:
turn left.
- Fly the styrofoam

If not, describe how it differed. varies
