Scalars and vectors

  1. Definitions

    1. Scalars are quantities that are defined by a magnitude
    2. Vectors are quantities that are defined by a magnitude and a direction

  2. Applying vectors

    1. Vectors can be represented graphically as an arrow that denotes the change in coordinates
    2. The resultant of two vectors can be determined graphically by placing the second vector at the end of the first
