The Fifth Edition of INQUIRY INTO PHYSICS maintains the perfect balance of quantitative and conceptual content by carefully incorporating problem solving into a discernible conceptual framework. The text integrates simple mathematics so students can see the practicality of physics and have a means of testing scientific validity. Throughout the text, Ostdiek and Bord emphasize the relevance of physics in our daily lives. This text is committed to a concept- and inquiry-based style of learning, as evidenced in the ExploreItYourself boxes, concept-based flow-charts in the chapter openers, and Learning Checks. Students will also find applied examples throughout the text, such as metal detectors, Fresnel lenses, kaleidoscopes, and smoke detectors. The text also periodically reviews the historical development of physics, which is particularly relevant as context for non-science majors.
