Prerequisites and corequisites

Prerequisite: Physics 161. Pre- or co-requisite: Math 264.


There will be four exams, three exams throughout the semester and a final exam. Each exam will contribute 25% to the final grade, with the lowest exam score dropped. The final exam will be a comprehensive exam. No make up exams will be offered. The remaing 25% of the grade will be Homework 15% and iClicker in class quizes 10%. Grades will be based on a curve where the class average will be a high C+. Grades will be posted using the three digit number generated when you register your iClicker.

Problem sets

Homework assigmments and due dates will be given in class and posted on this website. Assignments will be both Mastering Physics (MP) and written. You must register for a MP account. Our class ID is MPLIDKE51694. Solutions to non-MP problem sets will be posted to this website. MP grading policy: 6 attempts per question are allowed, no deduction for opening a hint. Credit is reduced 10% for each hour past the deadline. Incorrect answers give a 3% penalty or 100%/(number of answers) for T/F, multiple choice.

iClicker quizzes

Responses credited 0/1/2 points for no/incorrect/correct answer. I will ask 5 to 10 questions each day on material from previous lectures, preparatory reading, and presented material. iClickers must be registered before class on Wednesday, Sep. 3; points credited from then forward. CPS technical assistance available from Cathy Webster (webster@unm.edu). You must register your iClicker our PandA site, which will also take you to the iClicker site where you must also register your iClicker.
