General Physics Laboratory I
1. Objectives
The experiments in this laboratory course have been chosen to make the students to have hands-on experiences on basic principles of physics learned in the lecture and to prepare them for the advanced courses which will be taken in the future. In particular, these experiments have the following objectives
II. Lab Grades
The lab grades are given according to the relative excellency criteria.
The code of academic honesty and integrity must be honored during the whole lab experiments as in other classes. If it is found to be violated in your report or exam, the grade will be confiscated.

III. To The Students
Ⅳ. Laboratory Reports
V. The Relationship Between Students and Lab Instructor
You can discuss with your instructor during the lab or outside the class on the physical concepts and ideas you are working on. You are strongly encouraged to do so. In no case will the grade you will be affected by asking silly or trivial questions.
Ⅵ. Final lab test
At the end of the semester a closed-book lab test will be given. This test will contain questions where you will make experimental measurements similar to the ones given in th
Ⅶ. Other Regulations
1 . Food and beverages are not allowed in the lab.
2 . Clean your experiment area when you leave the lab, after finishing the experiments
