Ebook Matter, Energy, Force, and Work

The aim of this book, prepared during a period of eu forced quiet, is to present in a plain and logical manner some fundamental ideas and definitions of physics. The purpose is not to set forth the experimental side of the subject, nor to describe phenomena or laws; the intention is rather to assume a slight knowledge of these, and to proceed in an orderly manner to develop the concepts and definitions. Engineers and members of the other technical professions will find here, it is hoped, an aid to clearer thinking in their practical dealing with the subjects treated. Now, as never before, correct views of energy, force, and work are essential in these professions, through the progress of the application of science to the industrial arts. The extent to which these applications are daily brought home to the un technical members of the community is likewise so great that acquaintance with their underlying ideas is no less a matter of self-interest than of education. The book natu rally addresses itself most directly, however, to students and teachers in physics and chemistry, whether elementary or advanced, and of the natural sciences in general.
