Across
  1. 2. of attack- angle between airfoil + surrounding gas/liquid
  2. 4. force made by the propellers
  3. 6. Principle- air going under the wing goes faster than at the top, meet at back.
  4. 9. Rocket engine
  5. 10. attracts things
  6. 13. Structure with curved surface, to give better lift
  7. 15. Remain in one place in the sky
  8. 16. moving left or right while in flight
Down
  1. 1. rotation
  2. 3. Third Law- A body and the forces acting on it.
  3. 5. vertical blade, can be turned
  4. 7. control surfaces
  5. 8. Moving with a smooth, cautious movement
  6. 11. aerodynamic force, opposed to lift and thrust
  7. 12. aerodynamic force, wind goes faster under the wing then over
  8. 13. Movable flaps on the wings of airplanes
  9. 14. nose up
