Metropolitan Community College COURSE OUTLINE FORM (Page 1 of 6) Course Title: Course Prefix & No.: PHYS 111A Principles of Physics II LEC: LAB: 2.0 1.5 Credit Hours: 2.5 COURSE DESCRIPTION: Principles of Physics II is a continuation of the algebra based sequence of college physics. The course is taught as three courses (PHYS 111A, PHYS 111B, and PHYS 111C) that include lecture and lab. All three courses must be successfully completed to transfer as a semester length course. Students are strongly encouraged to stay with the same instructor throughout their physics series of five-week sessions. Topics include waves, sound, and electricity. COURSE PREREQUISITE (S): College-level reading, writing, and math proficiency and PHYS 110C RATIONALE: This course is intended for academic transfer students intending to pursue a professional career (physics, chemistry, biology, medicine, engineering, etc.). Students who are more comfortable in smaller classes but need a thorough knowledge of physics will benefit from this course.
