A physics professor offers instruction in physical science at a community college, four-year college, or university. As a professor, you can teach both undergraduate and graduate-level courses, depending on your qualifications. An associate professor (adjunct professor) works on a contract basis, while a faculty member with tenure has a career position at the university. Your duties in all physics teaching jobs include planning a syllabus for each class. You lecture, use exams to assess students’ knowledge, and oversee hands-on courses in a lab. At a university, your responsibilities include performing research and writing academic articles.
