PHY 102: University Physics II
This course fulfills the requirement of general education in Natural Sciences for graduation from the university for students of physics, engineering, and computer science. It forms a one-year standard course in University Physics. It is highly recommended that the students must have a fair amount of background in vectors, mechanics, and mathematics. Especially, knowledge of calculus will be required sometimes. The course will lay emphasis mainly on the physical description of processes rather than complicated mathematical derivations.
