The trajectories run along the maximum plateau of the squared wavefunction. The width of the wave packet increases with time from its initial value. In contrast to classical mechanics, particles are accelerated at the front and decelerated at the rear of the packet, because increases in magnitude as the amplitude of the wavefunction decreases. In the center of the packet the motion of the particle is uniform, which is the predicted motion for the classical case. Inside the wave the starting points for the particles are distributed according to the density of the wave at . The equation of the motion for the particles is given analytically.

On the right side, the graphic shows the squared wavefunction and the trajectories. On the left side, you can see the position of the particles, the squared wavefunction (blue), the quantum potential (red), and the velocity (green). The quantum potential and the velocity are scaled down.
