Laboratories:

During the semester you will complete 5 laboratory experiments (roughly one experiment every two weeks). The schedule of these experiments is as follows:

Experiment 1: September 9, 2024
Experiment 2: September 23, 2024
Experiment 3: October 7, 2024
Experiment 4: October 28, 2024
Experiment 5: November 11 ,2024 (data taking in Spurrier Gym) and November 25, 2024 (analysis)

Each experiment will take 2 hours and 40 minutes to complete. Currently, three laboratory sections are offered: Mondays between 2 pm and 4.40 pm, 4.50 pm - 7.30 pm, and 7.40 pm and 10.20 pm. All laboratories, except Part 1 of Experiment # 5 on November 11, 2024 which will be conductor in Spurrier Gym, will be conducted in B&L 407.

Office hours will be held during the lab time periods, usually during the week following the experiment. See the Phy 141 Calendar for details.

Lab reports are due on the Wednesday at noon in the week following the experiment. The due date is changed to the Friday at noon if there is midterm exam during that week. The lab reports must be submitted in pdf format using the phy141 laboratory drop box. Use the following format for the name of the lab report you are submitting: Exp#-LastName-FirstName-StudentID.pdf where # is the experiments number (1, 2, 3, 4, or 5), LastName is your last name, FirstName is your first name, and StudentID is you student ID number.

Each student needs to write and submit their own lab report in their own words.

Lab report due dates:

• Lab # 1: Friday September 20
• Lab # 2: Wednesday October 2
• Lab # 3: Wednesday October 23
• Lab # 4: Wednesday November 6
• Lab # 5: Friday December 6

NOTES:

1. You must complete ALL labs and ALL lab reports in order to get a grade for this course.
2. Late submissions are not accepted. If your lab report is late, you will receive a 0 for that report.

Office Hours:

Office hours start during the week of August 29, 2024.

Homework will be assigned each Friday. The homework is due the following Friday at noon. A fraction of the homework assignments are distributed and completed electronically, using WebWork, while the rest have to be dropped of in the Physics 141 homework locker, across from B&L 106.

Each homework set will consist of a number of quantitative problems that are based on the material discussed the previous week. The problem sets will reinforce the course material and it is critical for your survival in this course to complete the assignments and understand any mistakes you may have made while working on these problems.

Extra credit can be earned by completing various programming problems using the VPython programming language. The extra credit problems will be part of the regular homework assignments.

The final grade will be the weighted average of:

1. Final exam (20 - 25%)
2. Mid-term exams (15 - 20% each)
3. Homework (15%)
4. Lab (15%)
5. Quizzes (5%)
   

Midterm exams:

Tuesday September 17, 2024, 8.00 am - 9.20 am (Hoyt).
Thursday October 17, 2024, 8.00 am - 9.320am (Hoyt).

Exam policy:

As part of each exam you will receive a sheet of useful equations that cover the material that is covered on the exam.  You will be able to view/download the equation sheet before the exam so that you will be able to determine what information will be provided on the exam.  Do not spend your time memorizing formulas; it is more important that you understand how to use them!

Quizzes:

Quizzes will be given during lecture. Each quiz will contain 3 - 4 short questions, related to the material being discussed. You will submit the ansers using the polleverywhere tool (using either a web browser or using text messages).
