Your First Lab Session
Phys 101 and Phys 102 Lab for the summer semester will start on the second week of the semester and there will be a lab session every week. To find the detailed lab schedule click on the “Lab Schedule” link on the left. You are expected to be present in the lab on the date and time scheduled for you.
You will meet your Lab Assistants in your first lab session. You will be submitting your lab reports and all material related to your lab project to them. During your first three lab sessions, you will be introduced to basics of physics experimentation and to concepts such as accuracy, possible error, data collection, constructing graphs, and writing a report.
You Should get your lab manuals from the lab technician Sadettin Karateke in room SA-Z06. Since there will be a quiz given at the beginning of each lab session, it is important that you study the manual before you come to the lab.
Note for repeating students: If you have taken this course in the past and your lab grade is satisfactory, i.e., 60 or above, you have the right to apply for exemption. To do this click on the menu item “Request Exemption” on the left and fill in the on-line form. Be sure that your details are entered correctly so that we can find your lab grade from our files. Later, check and be sure that your name appears on the “Exemption List“.
General information and grading
Physics lab includes 3 experiments (45 % contribution) and 1 final project (55% contribution). The aim of the 3 experiments is to cover broad topic in the course and provide basic laboratory education.
- Experiments for Phys 101
Experiment 1 – Velocity and Acceleration (%15)
Experiment 2 – Angular Velocity and Acceleration (%15)
Experiment 3 – The Torsional Oscillator (%15)
- Experiments for Phys 102 and 108
Experiment 1 – Equipotential and Radial Electric Field Lines (%15)
Experiment 2 – Resistance and Capacitance of Circuits (%15)
Experiment 3 – RL Circuits and RLC Oscillations (%15)
The remaining part of your Phys. 101 and Phys. 102 Lab activity will be related to the development and carrying out of a project. The steps involved for this activity will be as follows:
(a) Find a project topic: Browse through your textbook and the syllabus of the course and familiarize yourself with the topics that you will be learning this semester. The names of the topics will be familiar to you from high school. Identify a measurement, a law, or another aspect of a topic which you may want to experiment on. You can also search the Internet for such Freshman level experiments. On the way to deciding what you want to do, check what equipment is available in the Labs. You can visit the Lab during your lab schedule, and ask the assistant about the available equipment. You are not restricted to using the equipment in the Lab, and you may decide to bring in additional materials for your experiment.
Your project must discuss the activities you will carry out, which must include measurements of physical quantities, tables displaying the collected data, analysis of this data to show how it fits the expected behaviour, possibly using graphs.
Sample Project topics for Phys. 101
Determine the equation of motion of an object
Demonstrate measurement of length in different length scale (mm, m, km)
Measure precision of your clock
Measure the gravitational acceleration
Demonstrate the work-energy theorem
Measure static and dynamic coefficients of friction
Measure centripetal acceleration
Measure the moment of inertia of an object
Demonstrate the parallel axis theorem
Demonstrate uniform and non-uniform circular motion
Demonstrate conservation of linear momentum
Demonstrate conservation of angular momentum
Use your smart phone to demonstrate a physical phenomenon you learn in the class
Sample Project topics for Phys. 102
Devise a method to measure the total charge on a small electrically conducting sphere.
Construct a circuit to be used to time 1 second, using R, L and C.
Build a DC electric motor or any other experiment to demonstrate the forces on a current carrying wire due to magnetic field.
Demonstrate Lens law
Demonstrate Faradays law of induction
Build an oscillatory circuit
Measure Earth’s magnetic field
Demonstrate basic principles of electromagnetic waves
Measure distance dependence of electromagnetic forces between two magnets.
Built and characterize an electromagnet
Characterize ferromagnetic materials
Study the physics behind the electric guitar
(b) Write a proposal for your experiment containing
- A title
- Your Name, Department, Course Code and Section
- A summary of the experiment you want to carry out, pointing out what you want to measure, the equipment you want to use or construct, and what measurements you will carry out.
- A summary of the research you have carried out which led you to this experiment. List the sources which you have used, relevant Internet links, etc.
- A detailed description of your experiment. This part should contain the following parts:
– a description of the setup you will construct
– the procedure you will follow to make measurements and obtain the data
– the structure of the tables you will use to record your data, etc.
– the procedure you will follow to analyse your data (what graphs, etc.)
– the theory relating your measurements to the results you want to demonstrate
- If you have to buy some items, you can request some amount of money for this. Depending on how good your proposal is, the University may agree to pay some of your expenses.
An example for a proposal can be found by clicking the link “Sample Proposal” below.
The proposal must be submitted as a printed copy to your lab assistant and in pdf format through the STARS/Moodle/Turnitin system.
To be able to do this, you must first create a Moodle account and then enrol (register) to the desired Moodle course pages. You can login the server using the “Moodle” button on their STARS screens. This must be done at least once at the beginning of the semester to create a Moodle account. Previous semester Moodle accounts will not work on the new server.
To access the course on Moodle: Log in the STARS system, Click on the “Moodle” button next to the name of the relevant course. If you experience any problems, please contact firstname.lastname@example.org.
You will receive feedback from the assistant within a week. If needed, make the necessary changes and re-submit your proposal before the deadline. You do not need to submit a revised proposal if your proposal is satisfactory and there are no changes made. In case you missed the deadline and did not submit a proposal, you can still submit your proposal as a revised one.
No feedback is given to the revised proposal.
(c) Carry out your experiment, collect your data and analyse your results
(d) Write a final report. Your final report should be structured similar to your proposal, with the addition of data analysis and a discussion of your results. Reports must be submitted through the STARS/MOODLE/Turnitin system.

Your Lab grade will be composed of the following components:
First experiment: (%15)
Second experiment: (%15)
Third experiment: (%15)
Project proposal (or revised proposal) (%15)
Final report (%30)
Poster presentation (%10)
- You may receive help for your proposals from various sources or discussions with other people, but anything you submit as Lab work must be your own work. Any form of cheating will result in failing the Lab, as well as disciplinary action.
- A selection of “best” experiments from all lab sections will be able to compete in a final presentation for ranking. The best ranked three experiments will receive special awards.
- You will lose points from a component for late submissions. You will fail the Lab if any component is more than one week late. In order to pass the Lab, your lab grade must be at least 60. Students who fail the Lab will receive an FZ grade from the course, independent of how they perform in their other coursework.
- You may ask for a reassessment of a component of your laboratory activity with the exception of the poster presentation. Reassessment application must be done within a week after the grade is announced.
- If your Lab grade is less than 90, you will not be able to receive an A+ grade from the course.
- The Labs will be available for you to work throughout the semester. You can visit the labs during your lab schedule; the assistant in the Lab can answer your questions about the available equipment as well as how you will be submitting your proposals and reports electronically.
