First-Year Focus

Which Physics Course is for Me?

Physics is a key foundation course for many areas of study. We have three introductory sequences to choose from—all of which have lectures, discussions, and laboratories:

  • 125-1,2,3 is taken by ISP students (and sometimes by other well-prepared students who are also enrolled in MENU or an equivalent Math sequence)
  • 130-1,2,3 is the "algebra-based" version of introductory Physics. Many BioSci majors choose to take 130.
  • 135-1,2,3 is the "calculus-based" version of Introductory Physics.  Some BioSci majors choose to take 135.  Physics majors, Chemistry Majors, Engineering students, and students in some special programs such as HPME must take 135. 
  • Physics 140-1,2,3 is intended for prospective physics majors and minors, and for others who want to learn physics in greater depth. Permission is required and may be obtained from Zosia Krusberg

When Can I Take Physics?

During the academic year, if you are taking Physics 125 ,130 or 140 , you must take the classes in fall, winter, and spring quarter. The sequence begins with 125-1/130-1/140-1 in the fall, continues in the winter with 125-2/130-2/140-2, and concludes with 125-3/130-3/140-3 in the spring.

If you are taking 135, we offer two options.

  • Sequence one begins with 135-1 in the fall and continues with 135-2 and 135-3 in winter and spring quarters respectively.
  • Sequence two begins with 135-1 in the spring quarter and continues with 135-2 the following fall and finishes with 135-3 in the winter quarter.

Both sequences are identical in content. We recommend that students complete Math 220 and 224 (or their equivalents) before taking Physics 135-1, so please keep this in mind when choosing which sequence to take.

Getting Started in the Major

The Physics major and minor are open to all undergraduates at Northwestern, with a range of concentrations to choose from. The major is designed to help students acquire a broad background in physics and related fields (for more information on why a Physics & Astronomy major may be the choice for you, please see this page).

Many of our students have taken physics before coming to Northwestern, but it is not necessary to have had a physics class before beginning the major. In the first year, most students take a year long series of introductory physics: Physics 140-1, 2, 3 or equivalent. Qualified students may take Physics for ISP with the consent of the ISP Program.

In addition to physics many first year students take a year-long series in calculus (Math 220, 224, 230). For further information on degree requirements, please see this page. A full list of undergraduate courses offered in the department can be found here.

AP Exam Credit

Students with AP scores of "5" will be awarded credit as follows:

Exam Credit
AP Physics I Exam Credit for Physics 130-1 and Lab Course 13X-1
AP Physics II Exam Credit for Physics 130-2 and Lab Course 13X-2
AP Physics C-Mechanics Exam Credit for Physics 135-1 and Lab Course 136-1
AP Physics C-Electricity & Magnetism Exam Credit for Physics 135-2 and Lab Course 136-2

Placement Exam Information

Credit for Physics 130-1, 2 and Physics 135-1, 2 may be earned by passing a placement exam. These exams are offered once a year, before Fall quarter classes begin in September. Exams for the 2018-2019 academic year will be offered on Monday, September 24, 2018 from 9:30 - 11:30 AM in Tech L211. For more information please contact Dr. Deborah Brown, Director of Placement:

The physics placement exam is not a requirement for students who plan to take first quarter physics at Northwestern.  However, students who pass a physics placement exam will receive NU transcript credit that satisfies the prerequisite for the next quarter of the sequence.

Research Opportunities

As a Physics & Astronomy major you will have the opportunity to work with one of our faculty members in doing original research. We encourage each student to discover an area of physics they particularly enjoy and identify a research advisor. Please see here for more information on undergraduate research opportunities.

Permission Numbers

If you are having trouble finding an open lecture or lab section for Physics 130 or 135, you may need a permission number to register. Please contact Yassaman Shemirani for assistance.
