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

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
10. two lines or vectors that form a 90 degree angle where they cross

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
