Introduction to Physical Science. 4-credit conceptually-oriented course with some algebra and with integrated laboratory component.. The course focuses on physics concepts.. Serves primarily . Speech-language Pathology Majors . Provides a physics-centered analysis of a broad range of astronomical systems that appeals to a large audience of advanced undergraduate students in physics and engineeringThis book gives a survey of astrophysics at the advanced undergraduate level. It originates from a two-semester course sequence at Rutgers University that is meant to appeal not only to astrophysics students but also more broadly to physics and engineering students. The organization is driven more by physics than by astronomy in other words, topics are first developed in physics and then applied to astronomical systems that can be investigated, rather than the other way around.The first half of the book focuses on gravity. Gravity is the dominant force in many astronomical systems, so a tremendous amount can be learned by studying gravity, motion and mass. The theme in this part of the book, as well as throughout astrophysics, is using motion to investigate mass. The goal of Chapters 2-11 is to develop a progressively richer understanding of gravity as it applies to objects ranging from planets and moons to galaxies and the universe as a whole. The second half uses other aspects of physics to address one of the big questions. While Why are we here? lies beyond the realm of physics, a closely related question is within our reach: How did we get here? The goal of Chapters 12-20 is to understand the physics behind the remarkable story of how the Universe, Earth and life were formed. This book assumes familiarity with vector calculus and introductory physics (mechanics, electromagnetism, gas physics and atomic physics) however, all of the physics topics are reviewed as they come up (and vital aspects of vector calculus are reviewed in the Appendix).
