As a result of the analysis of the methodical literature and training programs it is found out that they do not give coherence of all concepts necessary for the analysis and search of the decision of a physical task. The decision of the given problem is in representation of a subject domain in the form of ontology as the structure of the information inherent in ontologies, provides additional opportunities for information search. As the editor of ontology the program Protege 4.1 supporting format RDF/OWL is chosen. The sequence of actions is resulted at creation of ontology. The analysis of physical tasks is led and the basic concepts of physics necessary for the solvation of tasks are allocated. All concepts are presented in the form of classes, individuals and properties of attributes of individuals of the class. Using a theoretical material of the rate of physics, the hierarchical taxonomy of classes is constructed. On the basis of dependences of physical concepts attitudes between classes and-or individuals of classes are defined. The set of the RDF-statements received as a result of an establishment of communications, forms focused columns in which the tops are classes and individuals, and the edges are marked by attitudes. Ontology contains data on data, i.e. metadata. Ontology of a physical task received as a result of work is the base of knowledge, used for the solvation of tasks.
