There are two approaches to the problem of the dynamics of planetary nebulae. The first is based on the investigation of the velocity fields in the nebulae. The second can be carried out by studying the spatial distribution of the matter in these objects. In an ideal case both approaches can be united. However, data on the velocity fields in planetary nebulae still are very scarce and fragmentary and their rate of accumulation is rather slow.
