In this post we will see the book *Elementary Physics: Problems and Solutions* by *I. P. Gurskii*

The book is intended for those preparing for university entrance examinations in physics. The contents and sequence of topics are in keeping with the requirements for such examinations. The few sections beyond the entrance examination programme are marked by circles. In view of the introduction of the elements of higher mathematics to the high-school curriculum, some problems have also been illustrated using differential calculus. The author has endeavoured to present the basic principles of school physics in a compact form to help the candidates revise the entire course in the shortest possible time. All sections have been illustrated with problems to give a better understanding of the subject. Each problem and its solution is followed by one or more exercises on the same topic, the exercises corresponding to problems that have been solved in the text are assigned the same number.Those intending to use this book independently are advised to attempt the exercises after going through the theoretical part. The relevant solved problems should be consulted if difficulties are encountered while solving the exercises. After this, the exercise should be tried again, and if there is more than one exercise bearing the same number, another exercise (preferably the last one) should be tackled. In most cases, the last exercises in a series are the most difficult.

The book was translated from Russian by Natalia Wadhwa and was first published in 1987.
