Section CRN, Time and Place:
PHYS2341-04  CRN: 207778, Time and place:  Thur 12:00-2:45 pm, Meyer 121 (TA= )

Course Description:
This is the lab associated with Physics 2311 (Physics I) and Physics 2111 (General Physics 1). The student will perform experiments in Newtonian mechanics (projectile motion, collisions, conservation of energy, etc), Oscillatory motion (the pendulum), and thermodynamics (specific heat, thermal expansion).

Prerequisites: You should, ideally, be taking PHYS 2311 (or PHYS 2111) concurrently with this lab. It is also acceptable to have already taken PHYS 2311 (or PHYS 2111).

Manual and notebook: You need to buy the orange manual "Experiments in Mechanics, Waves, and Thermodynamics", the Physics I lab manual, for $13. You will also need to get a quad-ruled notebook for writing up your labs. We sell the notebooks for $2 although you can buy one elsewhere. Buy your lab manual and notebook ($15 total) from the instructor on the first day of class. Bring cash, preferably exact change. If that fails, then find Dr Pinkney during his office hours in SciAnx 111 during the first week.

EXTRA Materials
Error Propagation rules.
Example of error propagation (applied to calorimetry).  In this PDF file, I have taken a student's lab measurements (top left side) and used them to calculate the specific heat of copper, CCu.
Hyperphysics A nice supplement to your textbook which can be used to review concepts and equations.

  Your final letter grade is determined based on the average of your lab report scores.  Each lab is scored out of 10 points. The scores are determined by your TA with guidance (a rubric) from your instructor.  The instructor will take the scores from the TA and convert them into a grade. Typically, 90% and up is an A and 80-90% is a B. However, if the class mean is very high compared to other sections, the instructor may adjust the A-B cutoff. Usually, if any change is made, the cutoff is lowered to 89 or 88. But the cut-off could be raised to 91 or even 92% in order to keep different sections consistent.
Here is a rubric showing deductions for problems with lab reports.

Course Policies

Attendance  is essential for labs.  If you miss a lab completely you get a 0 for that particular lab.  If you miss and have a valid excuse (emergencies, sports or music activities, illness) let me know, and I will try to set you up to attend another section of the lab. If that doesn't work out, I may be able to arrange to let you into the lab at non-lab times. You have to work more independently when doing a make-up lab. There are 2 other sections of this lab to allow for these make-ups.

Sides A and B . We will be dividing our lab into 2, roughly equal sides. This is because we don't have enough lab apparati for 6-8 teams of students. For the first 4 weeks, everyone will do the same lab, but on the 5th week, side A will do experiment 4 and side B will do experiment 5. The following week, side A will do 5 and side B will do 4. (See the Schedule below.) The class will remain split until the 15th week. Use the lab time to gather good data and write up the report. Your notebook is left in the lab (on shelves) for your TA to find and grade.

Calculators. I encourage you to have a calculator in this lab.

Food and drink. Please do not bring food and drink into the lab. I want to avoid trash, clutter, and spills on the lab tables. A bottled drink that is stored in your backpack is acceptable.

ONU Health & Safety. We will be conforming to ONU's Fall, 2022 COVID-19 Safety Plan. Masks and social distancing are not mandatory across the board, but individual classes may require them based on student or instructor needs. Please have a mask on hand. If you think you may have a virus that spreads by respiration, wear a mask to be safe until you get tested. (Contact tracing is continuing and this may be required of you.) In this lab, you will be working in close quarters with others so you are encouraged to wear a mask. We are not requiring social distancing, but it is still a good idea to be spread out when you can. Let me know if you have to quarantine or isolate so that I can help you keep up with the class.
