This book contains a collection of Physics problems related to the material taught in the first year of high school. Most of them require complex handling of Physics concepts and, in some cases, special mathematical techniques. The first part of the book contains the statements of the problems. Each problem is accompanied by appropriate hints that highlight hidden and difficult points in its approach. The second part contains their detailed solutions. The book is aimed at students who want to tackle something unique and more challenging than the typical school curriculum. It aspires to be a valuable assistant in possible preparation for Physics competitions.
