Book: University Physics (OpenStax)

- Contributed by OpenStax
- General Physics at OpenStax CNX

*University Physics* is designed for the two- or three-semester calculus-based physics course. The text has been developed to meet the scope and sequence of most university physics courses and provides a foundation for a career in mathematics, science, or engineering. The book provides an important opportunity for students to learn the core concepts of physics and understand how those concepts apply to their lives and to the world around them.
