A localized free particle can be represented by a Gaussian wave packet. This Demonstration shows the spreading of a Gaussian wave packet, considering the effects of varying particle mass and momentum and initial width of the wave packet. Choose the parameters: mass, initial width and momentum, and see the evolution of the wave packet with time.
