Simple Nature

An Introduction to Physics for Engineering and Physical Science Students.

This is a calculus-based physics textbook meant for the type of freshman survey course taken by engineering and physical science majors, or for AP Physics C. It uses a nontraditional order of topics, with energy coming before force. For instructors who prefer the traditional sequence, there is a drop-in replacement for ch. 0-4, Mechanics, that covers force before energy.
