  4. 9. a type of relationship, where the second differences within y coordinates are equal
  5. 10. a force capable of balancing another force and producing equilibrium
  6. 12. the size, length, or amount of something
  7. 14. the vector sum of two or more vectors
  8. 17. when all external forces (including moments) acting on it are balanced
  9. 20. A point from which a body or an object starts moving
  10. 23. the path an object follows as it moves through space
