The Scalar (Dot) Product Two vectors can be multiplied to product a scalar resultant, called the scalar (or Dot) product. When using the magnitudes of the vectors: where  is the angle between vectors A and B When using vector components: Useful properties of scalar products: Example: The scalar product of the vectors of force and displacement is used to calculate work performed by the force
