  1. “Baby Vector Math” An Introduction to vectors By Amy Phillips

  2. Definition A vector is defined to be a directed line segment. It has both direction and magnitude (distance). It may be named by a bold-faced lower-case letter or by the two points forming it - the initial point and the terminal point. Examples: u or AB B u A

  3. Equal Vectors Two vectors are equal if they have the same distance and direction. u = AB B u A

  4. Opposite Vectors Opposite vectors have the same magnitude, but opposite directions. That is, the terminal point of one is the initial point of the other. u -u

  5. Resultant Vectors(adding) When vectors are added or subtracted, the sums or differences are called resultant vectors. Geometrically, we add vectors by placing the initial point of the second vector at the terminal point of the first vector in a parallel direction. The resultant vector has the initial point of vector 1 and the terminal point of the displaced vector 2. D B A C D AB + CD = AD B C A

  6. Resultant Vectors(subtracting) D We subtract a vector the algebraic way by adding the opposite. AB - CD = AB + (-CD)=AD C -(CD) B -(CD) A AD
