Problems are the cutting
edge that distinguishes between success and failure. Problems call
forth our courage and our wisdom; indeed, they create our courage and
our wisdom. It is only because of our problems that we grow mentally
and spiritually. When we desire to encourage the growth of the human
spirit, we challenge and encourage the human capacity to solve
problems, just as in school we deliberately set problems for our
children to solve. It is through the pain of confronting problems that
we learn.
- Morgan Scott Peck
This is the third semester of a three-semester, calculus-based physics sequence. The required prerequisites are PS 150 and PS 160 - Physics I and II for Engineers. We will cover electric fields and magnetic fields, Gauss's law, electric potential, capacitors, Ohm's law, Kirchoff's laws, Ampere's law, Faraday's law, Lenz's law, Maxwell's equations. Prerequisites: PS 160, MA 242.
Text: University Physics, 11th
edition,
by Young and Freedman.

Listening to lectures is not enough. All processes of learning are somehow connected to active participation, and the learning of physics is no exception. Therefore, it is imperative that you work diligently at your own desk. However, this does not mean that you should only work alone. I encourage you to form study groups and collaborate with your classmates.
Available at the Jack R. Hunt Library are the following items:
Understanding
Physics, by Isaac Asimov - a great science fiction writer
explains
physics.
Cartoon Guide
to Physics, by Gonick and Huffman - physical principles in a
visual format.
3000 Physics
Problems - lots and lots of practice quantitative problems.
Practice at problem solving is an important part of learning physics, especially for engineers. I suggest that you work as many problems as possible. I have assigned problems from each chapter, and I will post solutions to certain problems from the text. Problem solving techniques can be found here.
