Work and Energy 0 - Vector multiplication - the dot product

This video covers a basic overview of scalar multiplication of a vector, and the dot product. By the end of this video, you should:

1. be able to calculate a scalar multiple of any vector
2. be able to calculate the dot product for any number of 1D, 2D, or 3D vectors, if given the vectors in
(a) unit vector notation
(b) magnitude and direction notation
3. understand the physical significance of the dot produc
