Previous Vector Notation Next Adding Vectors
  • Position vectors describe the position of a point on a coordinate grid
  • Position vectors start at the origin and end at the position of the point
  • Position vectors can be represented as column vectors
  • Displacement vectors describe the change in position between two points
  • Displacement vectors can be represented using the notation from the first point to the second point
  • Displacement vectors are not dependent on the distance traveled along the path, only the initial and final positions
  • Vector addition can be used to rewrite a displacement vector as two different displacement vectors sharing a point
  • Displacement vectors can be expressed as the difference between position vectors
  • The displacement vector is equal to the position vector of the finishing point minus the position vector of the starting point
