### Course Overview

This course will cover such topics as projectiles, statics, Newton's laws, energy, collisions, circular motion and rotational dynamics. In addition, we will touch on some subjects related to celestial mechanics and general relativity. The Course Content and Outcome Guide includes more course detail and outlines the course prerequisites.

Our textbook will be *Physics (10th edition)* by Cutnell and Johnson. We will be covering chapters 1–9 in this course.

Each Monday session will be held in Room 232. This room contains the material used for the labs. Therefore labs will fall on the Monday meetings. The Wednesday sessions will consist solely in lecture and will be held in Room 234.

### Intended Outcomes

After completion of this course, students will

- Apply knowledge of linear motion, forces, energy, and circular motion to explain natural physical processes and related technological advances.
- Use an understanding of algebraic mathematics along with physical principles to effectively solve problems encountered in everyday life, further study in science, and in the professional world.
- Design experiments and acquire data in order to explore physical principles, effectively communicate results, and critically evaluate related scientific studies.
- Assess the contributions of physics to our evolving understanding of global change and sustainability while placing the development of physics in its historical and cultural context.

### Grading Scheme

Your total grade will be a weighted average of all the assignments in class. The weight for each category of assignments is in the following table.

Category | Weight |
---|---|

Weekly Quizzes | 25% |

Lab Participation | 25% |

Lab Write-up | 25% |

Final Exam | 25% |

#### Weekly Quizzes

I will assign weekly homework assignments but I will not grade them. However, the quiz problems will be similar to these problems so it is in your best interest to do them when assigned. These assignments are available on the website. The answers and some of my solutions are also available. Use these materials as you see fit.

The first half-hour of each Monday will be used for a short quiz. Although these problems may be taken from sources other than the homework, they will be comparable to them both in terms of content and difficulty level. These quizzes will be open book.

#### Lab Participation

The lab worksheets are available on the website. Please bring your own copy to work on. You will be required to record your data and observations, answer the questions, and return them to me before you leave. There will be no take-home work required with the labs. Only those present will receive credit for participating. There will be no make-up labs, but I will allow you to drop one as necessary. You will not be allowed to make up work by attending other physics classes.

#### Lab Write-up

Some of the labs will require a formal write-up. At a minimum this write-up must allow the reader to reproduce the experiment. In all cases these labs are rather qualitative in nature. I expect you to add at least one significant element to improve the quality of the experiment: tighter controls, more distinct trials, data graph, error analysis, etc.

A well-documented intent, procedure, data record, error analysis, and conclusion are all expected elements of the write-up. Here are the questions I will consider as I grade them:

- Is there a basic understanding of the lab?
- Is the data recorded clearly?
- Is the procedure reproducible?
- Is the theory correct?
- Is the analysis correct? (math/logic)
- Are sources of error identified correctly?
- Is the error propagation calculated correctly?
- Does the conclusion follow from the data?
- Are the future improvements thoughtful?
- Is the look and feel professional?

#### Final Exam

See the class schedule for the date of the final exam. The exam will be similar in nature to the weekly quizzes, taken from sources other than the book but similar in concept and difficultly level. The exam will be *open book*. If you need help remembering an equation or the value of some constant during the exam, I will certainly be willing to tell you—please don't hesitate to ask. You will be given the entire three hour period.

See PCC Grading Guidelines for more detail.
