Physics 50 example problems

Peter Beyersdorf

This is a video podcast of solutions to example problems from Dr. Beyersdorf's Physics 50 class at San Jose State University. Several episodes will be published each week including solutions to the previous week's homework and examples that may be useful in understanding current homework or preparing for upcoming exams.
