The four-volume series for physics in teacher training studies compactly and vividly covers the fundamentals of physics in all their breadth, without delving too deeply into theoretical aspects. It is tailored to the specific needs of aspiring physics teachers in secondary education. The focus is on understanding physical laws and their relevance in everyday life and modern technological applications. Each volume includes many color illustrations, examples, and estimations of quantities. Additionally, special topics from physics, mathematics, or the history of science are explored in depth. Volume 1 addresses classical mechanics according to Newton, starting with the kinematics and dynamics of point masses and extending to the motions of rigid bodies. From the statistical mechanics of many particles, thermodynamics follows naturally, primarily presented for ideal gases.
