### General Course Purpose

PHY 241 is a first semester of a two-semester calculus-based introductory physics with laboratory sequence. It provides the student with a broad understanding of the general concepts and principles of the physical universe, and prepares the student for advanced study in physical sciences and engineering through development of skills in problem solving, critical thinking and quantitative reasoning, and an understanding of the methods of scientific inquiry and experiments.
