## Magnetism Unit

As we enter the final phase of our course, you may have noticed that you have been doing more and more independent work.  One of our course goals has been to learn how to learn independently.  Our culminating activity in this endeavor will involve your undertaking a complete unit independently.  Of course, I am available to assist if you get stuck, but would like you to attack the unit on your own, with an understanding of what your learning goals are for this portion of the course.

Based on the goals provided, the following requirements and resources are available to you.  You are expected to set your own pace and schedule/ration your workload accordingly, based on the understanding that all requirements must be met and turned in at the beginning of class on March 29, the day of the magnetism exam.  All items are to be turned in simultaneously, stapled in a packet or placed in a folder with your name on it, including the attached cover page.

Unit activities include:

Watch MIT 8.02 Physics Lectures (Walter Lewin), available from iTunes U, web search, as well as DVD in class.

• Lecture 11: Magnetic Field, Lorentz Force, Torques
• Lecture 13: Moving Charges in B Fields, Cyclotron, Synchrotron, Mass Spec
• Lecture 14: Biot-Savart Law, Gauss’s Law for Magnetism
• Lecture 15: Ampere’s Law, Solenoids

Complete WebAssign: APC-Magnetism (turn in hard copy of your solutions).

Complete Lab: Magnetic Field in a Slinky (formal lab report as a group).

Complete two free response problems (turn in neat, complete solution):

• AP-C 2009 EM2
• AP-C 2005 EM3

Complete worksheet on Gauss / Ampere go to Battle (turn in)

Complete two quizzes:

• Magnetic Fields
• Biot-Savart and Ampere’s Law

In preparation for your magnetism exam, I would also recommend watching the APlusPhysics AP-C Magnetism Video Series:

## Momentum Independent Study Unit

As AP-C students in a college course, you have the skills and ability to work and learn independently. Toward that end, starting today we will engage in our first independent work unit, tying up our Momentum and Energy units. Between now and Thursday, Nov. 18, you are to:

1. Complete the C_Energy_Momentum Practice WS and achieve a score of 100%.
2. Complete the Impulse-Momentum Lab Activity
3. Complete the four-question Free Response packet and achieve a score of 100%.
4. Submit at least one APlusPhysics blog post. Comment on the post of at least one other blogger, and rate at least 3 blog posts.

You may work alone or in groups, and the order and scheduling of your activities is completely up to you. At the beginning of class on Friday, Nov. 18, prior to taking the exam, you are to place your papers for items #1,#2, and #3, all stapled together with your name, into the INBOX.

I will be available for guidance if you get stuck, but will recommend you utilize the available resources to help you independently first. These resources include, but are not limited to:

1. Textbook Sections 8.1-8.6
2. Physics Forums HW Help: http://www.aplusphysics.com/forums
3. Physics Videos: LearnAPPhysics.com
4. Physics Podcasts: MIT’s OpenCourseWare Physics (Walter Lewin) on iTunes

BLOG POST

Find and post an image, video, news/science story from a newspaper, podcast, youtube, etc. which illustrates the week’s topic, “Impulse and Momentum.” Include a paragraph which summarizes the connection to material we’ve been covering in class, or raises interesting questions relevant to the class. Previewing your entry prior to submission will allow you to check that your link works.

Why the blog assignment? From a former physics student:

“it’s a great way to connect with the physics community. The way that physics bloggers have been able to share news, advice, and commentary has already changed how this generation of physicists approach their craft. On a personal level, blogging has been a tool to help me codify my thoughts. Many of my physics-related posts were exercises in how to present topics effectively and later made their way into my presentations and write-ups. Once in a while someone will comment on something they think is neat, and that always makes me happy.”
