Problems and solutions of physics OKTV 2004-2016

The tasks and solutions of the National Secondary School Study Competitions of recent years and decades are an example for the newly growing generations in terms of how high the level of physics can be achieved by relying on secondary school physics, and how rich the problem-solving tools are. Therefore, we consider it important to collect and publish competition tasks and their solutions over and over again. In describing the solutions, the author discusses the strategy of the solution, the tricks of finding the way to the solution, the possibilities of controlling the result and, of course, the discussion of the solution. The usability of the book is greatly increased by the fact that in most cases the author gives the course of the solution and the final result in parametric form. The parametric solution highlights the thinking of the solution, makes the otherwise sometimes tangled derivation clear: in this way the physical content of the prescribed quantities and the logic of building the steps on top of each other can always be followed.
