The relationship between momentum, velocity, and position Video 5 of 10.

In this video I discuss the relationship between momentum, velocity, and position. The phase and group velocity are discussed. The momentum space representation of the wave function is derived and is shown to be related to the spatial representation of the wave function through a Fourier transform. The resulting coupling between the uncertainty in momentum and position is examined. This is video 5 of the 10 part series.
