# PHYS 111 - Introduction to College Physics I

3 Credit: (2 lecture, 2 lab, 0 clinical) 4 Contact Hours: [Math Level 3  and Writing Level 2 , or departmental approval]

This class is for those that need a beginning physics course. This class examines the topics of science, motion, force, energy, matter and waves. The material is presented in a way that is largely conceptual using simple mathematical relationships to promote understanding and problem solving. These concepts and scientific rigor are furthered with laboratory experiments.
