Written for the algebra/trigonometry based college physics course,this second edition captures the interest and imagination of both students and teachers by giving them a feeling for what physicists do and why it is important in today's world. The text accomplishes this by employing three important strategies. 1) The relevant applications of physics in areas such as health,medicine,world energy problems and the home environment. 2) The history of physics is introduced where appropriate to show how it has developed,how it is developing and who are the people who have made contributions. The incompleteness of our knowledge of physics is printed out to show students that physics is still lively and a developing subject.
