This book offers the reader over 750 problems concerning

the same subject matter as is treated in the two volumes of the

“Fundamentals of Physics”. The order of presentation of the theoretical

material is also the same.

The availability of a great number of

problem books based on the traditional school physics curriculum

prompted us to enlarge those sections which are absent from traditional

problem books, namely the dynamics of a rotating rigid body, the

elements of the theory of relativity and of quantum and statistical

physics, of solid-state physics, wave optics, atomic and nuclear

physics, etc. Problems dealing with astrophysics illustrate the

application of the laws of physics to celestial bodies.

The book contains a few problems requiring elementary

skill in differentiating and integrating, as well as some problems

to be solved with the aid of numerical methods, which

nowadays are being increasingly used.

The book was translated from the Russian by *Mark Samokhvalov* and was first published by Mir Publishers in 1980.
