This comprehensive introduction to calculus-based physics is written specifically with the aim of balancing the needs and wants of the students with those of the instructor. The authors, experienced researchers and teachers, represent both theoretical and experimental physicists. This text presents balance between theory and applications, between concepts and problem-solving, between mathematics and physics, and finally, between technology and traditional pedagogical methods. This work is also available with additional chapters - the Extended Version - and in split volumes: Volume I contains chapters 1-21 of the Extended Version; and Volume II contains chapters 21-46 of the Extended Version.
