  1. the vector sum of two or more vectors
    resultant
  2. a physical aspect that has only magnitude (mass)
    scalar quantity
  3. the force exerted by the pull of a taut rope or spring
    tension
  4. the perpendicular vectors whose sum is the resultant vector
    component vector
  5. the force of mutual attraction between two masses, especially an object and the earth
    gravity
  6. an arrow that represents the magnitude of a physical quantity though its length and points in the direction in which the physical aspects acts
    vector
  7. a downward force of an object due to earth's gravity
    weight
  8. the process of changing vector  into its perpendicular component vectors
    resolution
  9. a wind blowing in a direction opposite that of an aircraft's motion
    headwind
  10. two lines or vectors that form a 90 degree angle where they cross
    perpendicular 
  11. the force resulting from fluid friction between an aircraft and the air through which it is moving and that opposes an aircraft's motion
    drag
  12. the amount or size of quantity 
    magnitude 
  13. the force pushing an aircraft forward due to the actions of the aircraft's engines
    thrust
  14. a physical aspect that has both magnitude and direction, such as force
    vector quantity 
  15. force that results from the motion or pending motion of one surface across another and that resists that motion
    friction
  16. up, down, away, toward
    direction
  17. a wind blowing in the same direction as the aircraft's motion
    tailwind
  18. an SI unit for measuring force
    newton
  19. perpendicular to the earth's surface
    vertical
  20. the force on an object in contact with a surface that is perpendicular to the supporting surface
    normal force
  21. a method for adding vectors graphically
    parallelogram rule
  22. the downward force on an object due to earth's gravity
    weight
  23. the vertical upward force supporting an aircraft resulting from the motion of air passing over the aircraft's wings
    lift
  24. a wind blowing horizontally and perpendicular to the aircraft's motion
    crosswind
  25. an SI unit for measuring mass
    kilogram
