PHYS 102 :: Physics Illinois :: University of Illinois at Urbana-Champaign
The final exams have been scheduled. Section A1 will be Wednesday 5/13/2015, 7-10pm; section A2 will be Friday 5/15/2015, 1:30-4:30pm.
There will be additional office hours for the final exam. Check the office hour page.
The finals are cumulative and will cover all course material evenly. In addition to the usual study resources, here are a few items for the end of the semester:
- An extra practice "exam", that contains exam-like questions covering material from Lects. 20-28 can be found here.
- An optional homework #14, covering the last 3 lectures is in byteshelf.
- Prof. Chemla will hold an in-class review session on the last day of class, Wed. May 6. Late-semester material will be the focus of the review.
Here are links to the usual study resources:
- A formula sheet can be found here. This will be the same set of formulas given to you on the exams.
- Study sheets reviewing Lenz' & Faraday's laws can be found here and reviewing mirrors & lenses here. A study sheet on the different right hand rules can be found here.
- Practice exams from past semesters can be found here. Please be aware that different material was covered in semesters prior to FA14, so not all questions may be relevant. Video solutions to the FA13 exams are available in byteshelf (scroll to the very bottom of the main menu). Written solutions to selected midterm exams are available on Prof. Oono's site.
- A list of extra practice problems from the textbook can be found here. The textbook has answers to all the odd-numbered problems. This list will be updated periodically.
- Video solutions to selected homework problems in byteshelf. Simply click on the "Help" button next to the problem.
Note for Homework #13 due Tuesday, April 28: Question #1 "A tale of two particles" requires using several significant digits for the electron mass. Please use me = 9.11x10-31 kg. Not doing so will lead to rounding errors and an answer scored as incorrect.
Note: there was an error in the pre-lecture #13 video on "Lenz' law". The direction of the induced current in the loop was incorrect. A new, corrected video has been posted in its place in byteshelf. (If you are having trouble viewing the new video, make sure to clear your cache.)
Some general comments on approaching physics exams:
- Physics emphasizes conceptual understanding and problem solving skills, NOT memorization of facts. How well you do in the exams will depend on how you practice both skills when you review.
- Although math skills are important to solving physics problems, they should never replace a strong understanding of concepts. All problems should be approached starting from a firm conceptual basis, as opposed to “searching for the magic equation”.
With that in mind, here are some tips for studying for a physics exam:
- Review concepts. Pre-lectures, lecture slides, the textbook, and the discussion summaries are good places to review fundamental concepts.
- Practice solving problems. Past midterm exams are available for practice, as are extra textbook problems. Approach these questions from a conceptual basis first before working through any math. Review different types of problems, ranging from more conceptual-based (ex: lecture ACTs) to calculation-based (ex: Homework).
- Understand the formulas. Study the equation sheet and make sure you understand what each symbol represents, and when (and when not) to use an equation. Some formulas apply to specific situations only.
- Ask questions. Mastery of a problem means understanding the underlying concepts and being able to retrace each logical and/or math step(s) to the final answer. Getting the correct answer does not necessarily mean understanding how to solve a problem. Use office hours and review sessions to fill any gaps in the steps to solving problems.
Please see the course description for an explanation of how this course works. It may seem complicated at first, but all the pieces do work together to enhance understanding. The course description also gives important details on our policies for missed exams, labs & quizzes. Also, please consult the syllabus to help you keep track of what is due when.
We will be using i>clickers in every lecture. You can use either the older v1 or the newer v2 i>clickers. If you have not already done so, please register your clicker by visiting https://my.physics.illinois.edu/gradebook/. Having another student answer questions using your clicker is considered cheating.
The only course components eligible to be issued a grade of EX are discussions, labs and exams (except for the final). Please submit your excused absence no later than 14 days from your absence via the Excused Absences application. The count begins the day of your absence.For more information, please read the course description page.
