Since the Physics Department discourages students from changing
midstream from Physics 140 to Physics 125 or from Physics 240
to Physics 126, it is important that students choose the first
course of a physics sequence with care. Prospective engineers, physicists and chemists should elect Physics 140/240 rather than
Physics 125/126 because concentration programs in these areas
require the Physics 140/240 sequence. In the case of some departmental
concentration programs * (e.g., *biology) or in special
individual circumstances, students can elect or are encouraged
to elect the Physics 125/126 sequence. Some advisors will advise
all students who have had calculus to elect Physics 140/240. Physics
140/240 can be elected by all students who have had calculus, but it should be elected only by students who enjoy solving difficult
problems and who think that they will be good at it.

**125. General Physics: Mechanics, Sound, and Heat. *** Two
and one-half years of high school mathematics, including trigonometry.
Phys. 125 and 127 are normally elected concurrently. No credit
granted to those who have completed or are enrolled in 140 or
160. (4). (NS). (BS). (QR/1). *

Physics 125 and 126 constitute a two-term sequence offered primarily for students concentrating in the natural sciences, architecture, pharmacy, or natural resources; and for preprofessional students preparing for medicine, dentistry, or related health sciences. Physics 125 and 126 are an appropriate sequence for any student wanting a quantitative introduction to the basic principles of physics but without the mathematical sophistication of Physics 140 and 240. Strong emphasis is placed on problem solving, and skills in elementary algebra and trigonometry are assumed. While a high school level background in physics is not assumed, it is helpful.

PHYSICS 125 covers classical mechanics (laws of motion, force, energy and power) and mechanical wave motion (including sound waves). The final course grade is based on three one-hour examinations, class performance and a final examination. Cost:3 WL:5

**126. General Physics: Electricity and Light. *** Phys.
125. Phys. 126 and 128 are normally elected concurrently. No credit
granted to those who have completed or are enrolled in 240 or
260. (4). (NS). (BS). (QR/1). *

See Physics 125 for a general description of this introductory sequence of courses.

Physics 126 is a continuation of Physics 125; it covers electricity and magnetism, the nature of light, and briefly introduces atomic and nuclear phenomena. The final course grade is based on three one-hour examinations, class performance and a final examination. Cost:3 WL:5

**127. Mechanics, Heat and Sound Lab. *** Concurrent
election with Phys. 125 is strongly recommended. No credit granted
to those who have completed or are enrolled in Phys. 141. (1).
(NS). (BS). Laboratory fee ($25) required. *

Physics 127 is a laboratory course intended to accompany Physics 125 and provide a perspective on physics as an experimental science. Macintosh computers are used for data acquisition and analysis. Evaluation is based on participation and performance in the laboratory classes, and on written laboratory reports and quizzes. Cost:2 WL:5

**128. Electricity and Light Lab. *** Concurrent
election with Phys. 126 is strongly recommended. No credit granted
to those who have completed or are enrolled in Phys. 241. (1).
(NS). (BS). Laboratory fee ($25) required. *

Physics 128 is a laboratory course intended to accompany Physics 126 and provide a perspective on physics as an experimental science. Evaluation is based on participation and performance in the laboratory classes, and on written laboratory reports and quizzes. Cost:2 WL:5

**140. General Physics I. *** Math. 115. Phys.
140 and 141 are normally elected concurrently. No credit granted
to those who have completed or are enrolled in Phys. 125 or 160.
(4). (NS). (BS). (QR/1). *

Physics 140, 240, and 242 constitute a three-term sequence which examines concepts in physics fundamental to the physical sciences and engineering. This introductory sequence uses calculus, and, while it is possible to elect Physics 140 and Mathematics 115 concurrently, some students will find it more helpful to have started one of the regular mathematics sequences before electing Physics 140. The introductory sequence is primarily designed to develop a skill: the skill to solve simple problems by means of mathematics. Developing this skill requires daily practice and a sense for the meaning of statements and formulas, as well as awareness of when one understands a statement, proof, or problem solution and when one does not. Thus one learns to know what one knows in a disciplined way.

The topics in Physics 140 include: vectors, motion in one dimension, circular motion, projectile motion, relative velocity, and acceleration, Newton's laws, particle dynamics, work and energy, linear momentum, torque, angular momentum of a particle, simple harmonic motion, gravitation, planetary motion, pressure and density of fluids, and Archimedes' principle. Evaluation is based on performance
on three hourly examinations (see * Time Schedule * for dates
and times) and a final examination. Cost:3 WL:5

**141. Elementary Laboratory I. *** Concurrent
election with Phys. 140 is strongly recommended. No credit granted
to those who have completed or are enrolled in 127. (1). (NS).
(BS). Laboratory fee ($25) required. *

Physics 141 is a laboratory course intended to accompany Physics 140 and provide a perspective on physics as an experimental science. Macintosh computers are used for data acquisition and analysis. Evaluation is based on participation and performance in the laboratory classes, and on written laboratory reports and quizzes. Cost:2 WL:5

**240. General Physics II. *** Phys. 140; prior
or concurrent enrollment in Math. 215. Phys. 240 and 241 are normally
elected concurrently. No credit granted to those who have completed
or are enrolled in 126 or 260. (4). (NS). (BS). (QR/1). *

See Physics 140 for a general description of the introductory physics sequence.

The topics covered in Physics 240 include (1) classical electromagnetism:
charge, Coulomb's Law, electric fields, Gauss' Law, electric potential, capacitors and dielectrics, current and resistance, electromotive
force and circuits, magnetic fields, Biot-Savart Law, Ampere's
Law, Faraday's Law of induction, simple AC circuits; and (2) geometrical
and physical optics. There will be three hourly examinations (see * Time Schedule * for dates and times) and a final examination.
Cost:3 WL:5

**241. Elementary Laboratory II. *** Concurrent
election with Phys. 240 is strongly recommended. No credit granted
to those who have completed or are enrolled in 128. (1). (NS).
(BS). Laboratory fee ($25) required. *

Physics 241 is a laboratory course intended to accompany Physics 240 and provide a perspective on physics as an experimental science. Evaluation is based on participation and performance in the laboratory classes, and on written laboratory reports and quizzes. Cost:2 WL:5

**415. Special Problems for Undergraduates. *** Permission
of instructor. (1-6). (Excl). (INDEPENDENT). May be elected for
a total of 6 credits. *

This course emphasizes experimental or theoretical research under the supervision of a faculty member. Generally a small facet of a large research undertaking is investigated in detail. This is an independent study course, and instructor permission is required. The appropriate form is available in the Physics Student Services Office, 2061 Randall Lab.

**496. Senior Thesis I. *** Permission of departmental
concentration advisor. (2-3). (Excl). (INDEPENDENT). *

concentration advisor. (2-3). (Excl). (INDEPENDENT). *

A continuation of Physics 496. Students who do not complete their thesis research in Physics 496, may continue to 497. If continuing, a grade of Y is given for Physics 496 and a final senior thesis grade given upon completion of the research.
