Description and Aim of the Course
The Physics for Non-scientists course is the first step in your career. It covers a large amount of
material in two semesters. The course places the necessary emphasis on practical problem solving.
The information you will learn here will form a basis upon which you will build up new blocks in
the future. It is a basic course however, I expect that those of you who succeed in this course will
feel more comfortable in your career as the course gives uysable tools and problem solving
strategies. It is a course designed to serve you well in many of your future endeavors.
The course is intended to provide you with an environment in which you understand the physical
world around you so that you can extrapolate these information and solve specific design problem.
Hence, the course aims at:
• building a link between theoretical physical concepts you learn in lectures and the real physical
world by providing an experimental/observational atmosphere where you can “feel” and “see”
the physical concepts,
• orienting the course mainly on discussions so that you can become an important subject as a
contributor in the course,
• using the physical concepts and principles so that you understand why an object is designed the
way it is, and
• presenting the concepts so that you have the feeling how an object works.
To achieve these goals the course will have the following aspects:
• Lecturing and Laser Disc Demo:
The physical concepts will also be discussed during lectures and you are expected to attend
these lectures and be a part of the foregoing discussions
Physics demos will be presented to you by the lecturer so that you have the chance to “see” and
“feel” the physical concepts which are given during the lectures.
• Design Discussions:
You will be presented different consumer products and the necessary physical concepts
underlying these products will be discussed. Every student will be given a product at the end of
the semester and you will be expected to submit a research report about this product.

Details of the Course and the Assesment
• Attandance: (10 points)
The attendance will be calculated based on the submitted quiz papers. No extra attendance
sheet will be signed.
• Quizes: (15 points)
At the end of each lecture hour you will be given a quiz question. Each quiz question will be
marked with either 0 points (failed to answer) or 1 (partially answered) or 2 (fully answered).
• Product lectures: (25 points)
The tutor (Evren Akar) will present several consumer products during the semester. Interaction
between tutor and students will be through the ”METU Online” e-learning web pages. Details
of these lectures will also be e-mailed to your METU account.
Student Study:
During this course you will have the chance to practice how to work and do research on a
product; Each student will be assigned a consumer product. For this product you have to submit
a report. Students are required to do these analysis by using Physics terms and concepts which
are discussed during lecture hours. The report will be assesed concerning the following aspects:
– Submission (1 points)
– Content (3 points)
– Research (3 points)
– Physics language (3 points)
• Mid-terms: (25 points + 25 points)
Approximate exam dates will be arranged according to the following schedule:
1 week for general introduction
5 lecture weeks (plus product lecture study)
mid-term exam week
5 lecture weeks (plus product lecture study)
final exam week
The mid-term and final exams will have the same percentage however they will cover different
content. In the mid-term the ratio of lecturing/product work will be 3/2 and in the final it will
be 2/3.
Exams will be closed book classical written exams. However, you are allowed to prepare a
cheating sheet. The format of the sheet is: 1) You can only use at most one double sided A4
paper, 2) You can only use sheets hand written by yourself. No photocopy or printer output is
allowed, 3) At the end of the exam the cheating sheets will be attached to the exam papers.
