## Physics

Requirements for the major: 9 units above the introductory level, including the six core courses 200, 201, 210, 240, 245 and 320 and 3 additional units in Physics or Astronomy (above the 100 level), at least 2 of which must be at the 300 level. In addition to those nine units, students must complete Mathematics 221, 222. Additional recommended Mathematics courses: Mathematics 228, 241, and 324. Physics 200, 201 and 210 should be taken prior to the beginning of the junior year. Physics 240 and 320 should be taken prior to the beginning of the senior year.

After the declaration of a physics major, no physics courses or courses counted towards the major may be elected NRO. Prospective majors should consult the department as soon as possible and are strongly advised to elect physics and mathematics as freshmen. Those majors planning on graduate work in physics are strongly advised to complete Physics 310 and Physics 341 and are encouraged to consult with the department concerning other courses in the natural sciences which may supplement the physics major.

**Physics Teaching Certification:** Those planning certification for high school physics teaching must have one of their 300-level units as a thesis or independent project (Physics 300 or 301) and 1/2 unit each of lab development (Physics 298) and lab apprenticeship (Physics 298). Additional courses in Education and Psychology are required for certification. Consult Ms. Schwarz.

**Advisers:** Mr. Bradley, Mr. Daly, Ms. Magnes, Ms. Schwarz.

**Correlate Sequence in Physics:** Students majoring in other programs may elect a correlate sequence in physics. The requirements for the correlate sequence consist of 4 units of physics above the introductory level (Physics 113/114 or equivalent), 2 of which must be chosen from the following pairs of courses: Physics 210-310, 210-320, or 240-341, Astronomy 222-320, Astronomy 220-320. The two remaining units must be at the 200- or 300-level in physics. (Note that Physics 200 and 210 are prerequisites for Physics 320.) A working knowledge of calculus is required for Physics 113/114 and for all courses above the 100-level. The NRO option may be used for at most one course to be included in the physics correlate sequence.

## I. Introductory

### 100b. Physics in Motion(1)

Motion is much of what physics is about and motion can be seen all around us. Recent technological advances in digital video and computers allow many motions to be filmed, analyzed and studied. We begin by filming a variety of objects in motion and uncover the physics inside. In the second half of the semester groups focus on topics (of their choice) of interest to K-12 students. Each group produces a DVD, incorporating video, text, and other media into the project to help explain the physics behind the scenes. The DVD project is presented in local K-12 schools as a final exercise. Ms. Schwarz.
