- Vectors represent motion
- Vectors have a magnitude and a direction
- To add vectors you add head to tail.
- The triangle formed by the vectors give the resultant vector
- To add vectors algebraically you add components
To find the magnitude of a vector you do (x2-x1, y2-y1)
Ex. A(11,6) B(12,7) Find vertices AB
(7-6),(12-11)
AB=1,1
