Course Outline

How does the moon orbit and what makes it do this? Is this related to the motion of falling objects? How much useful work can one extract from an engine? What is the nature of light? What is the mechanism by which ultraviolet light causes damage to skin cells? Why are we convinced that atoms exist and from what are they built? What are the fundamental particles from which all matter is built? How is time related to space? Are there limits to our universe and could we learn them?

Physics addresses such questions and provides a scheme by which we can picture and understanding the basic workings of the natural world. Physics emerged as a scientific (rather than philosophical) discipline in the early 17th century and since then physicists have been able to describe much of the natural world in terms of a small number of fundamental principles. Although much of the motivation for this has been curiosity, physics has remarkable practical consequences. For example, the theory of electricity and magnetism is vital to the operation of electrical devices and we are indebted to quantum mechanics for the construction of the components which enable lasers and computers to work.

Phys 111 aims to provide you with an understanding of some of the fundamental ideas from classical physics and to enable you to apply these to understand features of the natural world. Classical physics is that which was developed before 1900 and is good at describing much of the phenomena that you may observe on an everyday basis.

Course Structure

Phys 111 meets four times per week. The Monday, Wednesday and Friday meetings will be in lecture format. You will be expected to read the relevant sections of the text beforehand and attempt designated exercises in the text.

The Thursday meeting will consist of a discussion session during which you will work in small groups (with the instructor's help) on assigned problems. You will be expected to attempt the assigned problems before the Tuesday class meeting. There will be a short minute quiz covering the material at the end of the discussion session.

Homework Assignments

Apart from the Supplementary Exercises, problem numbers all refer to Young, College Physics, 10th ed. Supplementary Exercises can be found by clicking the link.

Homework Solutions

Homework solutions are posted on the course K drive. You can access these from any computer connected to the CMU network. The directory depends on your section number but can be found under K: ->PHYS111 -> 00X-YYYYY -> Share -> homework.

Quizzes

There will be a short quiz at the end of each of each Thursday discussion session. Quiz solutions are posted on the course K drive under K: ->PHYS111 -> 00X-YYYYY -> Share -> quizzes. You can access these from any computer connected to the CMU network.

Warm Up Exercises

There will be warm up exercise, approximately once per week, due by 8:00am. Exact dates will be announced by the instructor closer to the time. Warm up exercises are hosted on Desire 2 Learn (D2L).

Exams

There will be three 50 minute exams during class on the following dates: 12 February 2016, 25 March 2016 and 22 April 2016. There will be a comprehensive final exam on 9 May 2016 (Section 002) or 11 May 2016 (Section 001). Solutions to the exams for this semester will be posted below after the exams have been graded.

Supplementary Reading

There are many additional texts which are potentially suitable for this course. The following is a selection.

1. Conceptual Physics

   1. A. Hobson, Physics Concepts and Connections, Addison-Wesley. Typically used for conceptual physics courses and technically much simpler than what is required for this course. This may be a useful reference for getting a broad picture of physics.

   2. P. G. Hewitt, Conceptual Physics, Addison-Wesley. Another conceptual physics text and also at a lower mathematical and technical level than required for this course. Covers more of the standard introductory physics topics than Hobson.

2. College Physics

   1. R. A. Serway and J. S. Faughn, College Physics, Thomson/ Brooks Cole. Similar to other undergraduate college physics texts.
