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 be taking PHYS 2311 (or PHYS 2111) concurrently with this lab. It is also acceptable, but not ideal, to have already taken PHYS 2311 or PHYS 2111.

Manual: 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 notebook (from a store) from which you can cleanly remove sheets to be turned in. The ideal notebook would have perforated pages and be quad-ruled (graph paper). Buy your lab manual 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.

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.

Groups and teams . We will be dividing our lab into 2, roughly equal groups. This is because we don't have enough lab apparati for 6-8 teams of students. It also helps with social distancing. Those with last names beginning with A-G will attend for the first 1 hr 20 minutes, H-Z will attend for the last 1 hr 20 minutes and there will be a 5 minute transition period in the middle. Use the lab time to gather good data. You don't have to complete the lab write-up during class time. The write-up is turned in at the start of the next week's lab.

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.

COVID-19 Safety Plan. ONU updated the Safety Plan for 2021-2022 in January, 2022. The key point is that all students must be masked in class. Keep the nose covered, please. We are not requiring social distancing, but it is still a good idea to be spread out in our seating. Let me know if you have to quarantine or isolate so that I can help you keep up with the class.
