Passage 1
University Physics is intended for students of science and engineering. Primary emphasis
is on physics principles and problem-solving; historical background and specialized practical
applications have been given a place of secondary importance. Many worked-out examples and
an extensive collection of problems are included with each chapter.
In this new edition, the basic philosophy and outline and the balance between depth of
treatment and breadth of subject-matter coverage are unchanged from previous editions. We
have tried to preserve those features that users of previous editions have found desirable, while
incorporating a number of changes that should enhance the book’s usefulness.
The textbook is adaptable to a wide variety of course outlines. The entire textbook can be
used for an intensive course two or three semesters in length. For a less intensive course, many
instructors will want to omit certain chapters or sections to tailor the book to their individual
needs. The arrangement of this edition facilitates this kind of flexibility.
Conversely, however, many topics that were regarded a few years ago as of peripheral
importance and were omitted from introductory courses have now come to the fore again in the
life sciences, earth and space sciences, and environmental problems. An instructor who wishes
to stress these kinds of applications will find this textbook a useful source for discussion of the
appropriate principles.
In any case, it should be emphasized that instructors should not feel constrained to work
straight through the book from cover to cover. Many chapters are, of course, inherently
sequential in nature, but within this general limitation instructors should be encouraged to
select among the contents those chapters that fit their needs, omitting material that is not
relevant to the objectives of a particular course.
