Physics 25, Spring 2012 - Prof. Nelson

Final is Wednesday, June 13, 4-7pm, 1640 Broida. Bring a bluebook, calculuator, one sheet of notes. The problems will be very much like those on the homework.

Last problem set assigned 5/30, due at the final 6/13

Times and People

Welcome to Physics 25 for Spring, 2012. Our lectures are MWF 1-1:50 pm in Broida 1640. Attendance is required at section, Thursday 1-1:50pm in Psychology 1171, taught by Curt Nehrkorn.

Material

We plan to cover material from Chapters 45-56 in Halliday, Resnick, and Krane... 4th edition.

Required Items

The required items are:

  1. Halliday, Resnick, Krane Volume 2 Extended, Physics 4th Edition. Get a used one... also a bunch are on reserve in the Library.
  2. Please register your iClicker... use your Perm # as your Student ID.
  3. Calculations must be done, so a scientific calculator (must have trig, exponential, etc) is essential.

Recommended Items

A laptop is very useful for a variety of reasons, among them... it is really nice to do calculations in Excel.

Problems

The heart of this course is the working of problems. Much of the discussion sections will consist of doing problems. Weekly problem sets will be due Mondays, to be turned in to the Physics 24 boxes in the lobby of Broida Hall, by 5pm. The problems are generally not the type of problems that you can get done in a few minutes... some may take a few hours, so start early, and utilize our office hours. You are also encouraged to work together to figure out how to do problems, but, you must write up your own solutions independently.

Unfortunately, solutions can be found sometimes on the web. Copying such solutions and turning them in is forbidden, and will hurt you when you try to take the tests for this course, because you can't copy during the test. And often the solutions on the web are wrong.

Write up your solutions carefully and neatly. Generally, make a clear diagram, introduce algebraic variables for unknowns, and solve for answers symbolically. Plug in numbers at the end, and, do some cross checking as well as consideration of limiting cases (like, what if each mass in the problem becomes very large or very small?).

If homework is late by more than two days from the due date, you will get no credit. If you turn it in up to two days late, you will receive 50% credit.

Grading and Tests

The plans for grading are: Class Participation (measured in part with the iClickers), 10%; Problem sets, 25%; Midterm 25%; Final 40%. Current plan is for one midterm, on Monday, May 7. The final is Wednesday, June 13 from 4-7pm in Broida 1640.

Office Hours

Prof. Nelson will hold office hours Thursday 3:30-5:30pm. Curt Nehrkorn will hold office hours in the PSR Monday 3:30-5:00pm, and Thursday 2:00-3:30pm.

Treat Everyone with Respect

Some serious issues of harassment have from time to time arisen in our classes. If you feel you have experienced hazing or harassment, this document can help you do something about it.
