Book Details
Reflecting the latest developments in the field and featuring an updated full color art program, INQUIRY INTO PHYSICS, 8th Edition, continues to emphasize the inquiry approach to learning physics by asking students to try things, to discover relationships between physical quantities on their own, and to look for answers in the world around them. To build conceptual understanding, this arithmetic-based text includes Physics to Go activities, Concept Maps, and periodic conceptual quizzes. At least one Applications feature in each chapter demonstrates the use of physical concepts developed in the chapter in areas such as astronomy, medicine, environmental science and cultural studies. The text also reviews the historical development of physics and offers vignettes about the scientists who made new discoveries possible, elements that are particularly relevant as context for non-science majors.
