Across
  1. 2. when we find the dot product of 2 vectors, the result is always a XXX
  2. 5. two vectors have the same magnitude but point in opposing directions are called XXX vectors
  3. 10. the process of replacing a single force by 2 component forces is called XXX of forces
  4. 12. four determine the angle between these 2 vectors
  5. 13. determine the value of q that will make the vectors perpendicular
  6. 16. is a cross product in XXX form
  7. 17. this is the XXX property
  8. 18. this s the XXX law
  9. 19. vector multiplication is commutive
  10. 20. if a line is represented by XXX it is a XXX equation
Down
  1. 1. two planes whose normals are n and n are XX if
  2. 3. 2 vectors a and b whose resultant are the XXX forces of r
  3. 4. the quanitity is called a XXX combination of vectors a and b
  4. 6. a vector is a mathematical quantity having both magnitude and XXX
  5. 7. the XXX of several forces is the single force that can be used to represent the combined effect of all forces
  6. 8. if the dot product of 2 vectors is 0 then they are XXX
  7. 9. a XX vector with magnitude 1
  8. 11. then all of these vectors are XXX
  9. 14. the XXX product is defined as the vector that is perpendicular to both vectors a and b
