Hi Folks,

The Homework for Monday was the sheet I gave out at the end of class.

Have a nice long weekend.

thanks,

Micah

Hi class,

Your HW for Thursday – you have a trip tomorrow – is:

P.437 Problems #1-3

Thanks

Micah

Hi folks,

We have entered the world of electric charge!! The HW for Tuesday is in the texbook:

P.434 Review Questions #1, 3-8, 11-13

P.435 Exercises #1-5

Please remember that answers must be in complete sentences. When answering a question you must also back up your answer (why is your answer correct?) if possible. Also, on any computations (math), you must show your work!

Some notes: Like Charges repel, opposite charges attract Charge of an Electron (-) is equal in magnitude but opposite in sign, to the charge of a Proton (+) Atoms usually have as many Electrons as Protons, so the Atom has a zero net charge. If an Electron is removed from an Atom, it has one more positive charge (proton) than negative charge (electron) and is said to be positively charged .

A charged Atom is called an Ion. A positive Ion has a positive net charge. A negative Ion is an Atom with one or more extra Electrons (negatively charged).

Conservation of Charge – Charge is never lost, no electrons are ever created or destroyed. Electrons move from one place to another. You will need your notes and the textbook to do the homework. Use the textbook as a resource, it is a handy when you need to remember the formula for Coulomb’s Law etc . . .

This is due tomorrow January 12th

Thanks

Micah

Hi class,

I have some questions for you to answer about Work, Power, Energy, Potential Energy, and Kinetic Energy. The attached worksheet is identical to one you will receive in class on Tuesday January 5th, 2010.  Please answer all parts of questions 1 and 2 for Wednesday (1/6).  On Wednesday we will discuss the Universal Law of Gravity and for Thursday (1/7) you will answer question 3.

Hello class from paternity leave in Brooklyn!!

I hope you all had fun building an AC generator! I know I did.  I just wanted to say it was a great term, and I enjoyed having class with you all!

Attached is your final assignment here just in case. Preethi should have given this out for you to answer as you did your lab. Download it here:  AC Generator Lab

Each group should send a picture or short video of their generator in action. I’d love to have you email it to me with the answers to your questions! Each group should send me ONE answer sheet that represents the work of their whole group. Due via email Tuesday 12/8 by Noon!
There is a diagram for #7, if you can take a picture and attach it great.  If it’s not working, hand it in to Preethi or put it in my box!

Finally – Here is your last take home quiz!! It is only a few questions.  Please put your completed quiz on my desk by the end of the day monday 12/14/2009!

Thank you and see you in January!!

Micah

Hi all,

Your homework for tomorrow is the handout I gave in class today!

Upcoming – Presentation on Monday (Tesla Inventions) Please see me if you have not chosen an invention!

Thanks

Micah

OK,

So please email me at mdgottlieb@lrei.org with the invention you would like to do a presentation on next Monday 1/23/2009.  You must speak for 3 minutes max (with visual aids -Powerpoint, etc . . ) explaining what the invention you chose does, and how it works (to the best of your ability).

A few of you have picked your inventions, here are some more to think about:

Neon and Fluorescent light

Electric Arc Lamp

Electromagnetic motor

Method of obtaining DC from AC

Improvements to the Electric Railway System

and many more!

Thanks

Micah
