This updated edition of a popular text contains new information on the relationship between physics and the
workings of the body. New material on forces in dentistry has been added, and an entire chapter is devoted to the
physics of the ear and hearing, with more detail on the function of the inner ear. Many new illustrations have
also been added.
This book is intended primarily for students who plan to make a career in some field of medicine. The authors rely
on basic physics principles to promote an understanding of the function of the various organ systems of the body
such as the eyes, ears, lungs, and heart. Although it was written primarily as a text for students who have some
knowledge of elementary physics, it will be interesting and understandable to any person who is curious about how
his/her body works. The mathematics is at the algebra level. Several new problems have been added to this new edition
along with answers to all the problems
