HOMEWORK

There are two parts to the homework: mastering physics (www.masteringphysics.com) and written homework. The written homework is assigned on this page. All problems listed are from the text book given on the syllabus unless posted. The notation followed is C.NN where C is the chapter number and NN is the problem number. Hence 5.4 stands for 4th problem from chapter 5.

Mastering physics homework problems are assigned from www.masteringphysics.com. Please go to the website and register as a student using your student access code that either came with the textbook or purchased separately. Enroll in the course index that was sent to you over email.

INSTRUCTIONS

Complete instructions on how to go about solving the homework are given in this section of the syllabus. We will select and grade in detail two problems from every written homework which aree worth 6 points each. For the 6 point problem, points will be taken off for: incorrect method, insufficient explanations (upto 3 points!), lack of units(-1/2), lack of direction and magnitude if vectore quantities(-1/2), for not showing the equation that you use (in its complete form) to start calculating a particular quantity(-1 to 2), lack of staples(-1), not being neat and tidy(-1), not writing your name, section number, homework numbe (-1 for the first time and -2 thereafter).

The rest of the problems assigned on the homework will be graded out of 2 points each.  An correct solution gets 2 points, a valiant attempt "almost there" gets 1.5 points, while a good attempt (right method with the correct equations, correct picture) could get 1 point, some attempt gets 0.5 points. 1 point (out of 2) will be taken off for lack of explanations. Often, I may suggest work problems that may help students to better understand some concepts.  These problems are not due in class or will not be graded, although it would be extremely beneficial to work through them. These solutions to these problems will be put up on the the elms website.

Some of the problems might have extra parts and these are mentioned at the end of the table. But you can access them by clicking on the link adjacent to the problem.

Some of the written homeworks may be changed to mastering physics homeworks depending on the load on the grader.

Polite advise/reminder/request blah blah blah...

If you are not doing well on the homeworks consistently, then something is not right and needs to be fixed. This can only happen if you talk to us. The earlier the better.
