Vectors

Introduction to vectors
Introduction to vectors. A vector is a quantity that has both a magnitude (or size) and a direction. Both of these properties must be given in order to specify a vector completely. Adding and subtracting vectors and using them in geometry is described.Length: 33 minutes 
Cartesian components of vectors
Cartesian components of vectors. Any vector may be expressed in Cartesian components by using unit vectors in the directions of the coordinate axes. These unit vectors in two dimensions and in three dimensions are described.Length: 20 minutes 
The Scalar Product
The scalar product. One of the ways in which two vectors can be combined is known as the scalar product. When the scalar product of two vectors is calculated the result, as the name suggests, is a scalar rather than a vector.Length: 45 minutes
