The Vector Calculator is provided in support of our Physics Tutorials on Vectors and Scalars which explores addition and subtraction of vectors, multiplication of a vector by a scalar, dot (scalar) product of two vectors and the vector product of two vectors with practical working examples and formula. A list of the supporting Vector and Scalar Physics Tutorials is available at the bottom of this page. This calculator will calculate:
These results will be used to find the following physical quantities:
