### General Course Purpose

PHY 201 is the first semester of a two-semester algebra-based introductory physics with laboratory sequence. It provides students with a broad understanding of the general concepts and principles of the physical universe, and prepares the students for their future careers through development of skills in problem solving, critical thinking and quantitative reasoning, and an understanding of the methods of scientific inquiry and experiments.
