#1 Click on the link below to get a great visualization of how the centripetal force and tangential velocity combine to create a circular pathway.
Spend a few minutes watching the animation and reading the text.

For the quiz - you should be able to: describe the centripetal force and its effects, describe what happens when this force is removed, [| the "Center-seeking" Force]

At the bottom of the same page, click on the red arrow in the right corner. Spend a few minutes here learning about the "False" froce. For the quia - you should be able to: describe why the centrifugal force is not a true force, describe its effects, re

#2 Visit the sites listed below. **Record observations and answers (anything that is bold)** as indicated on a sheet of lined paper.
[|Lights Out] Read the instructions on how to play. Try to count the number of turns it takes for you to break all the light bulbs. **Write that down**.
 * Describe how the disc moves when you let go of the string**.

[|Slinger] After the advertisement plays, you can select to play in normal mode or survival mode.
 * What is the purpose of this game?**
 * Describe what happens when you move your mouse in a circular motion.**
 * What kind of upgrade did you select? Describe how this upgrade is different than the original.**

So sick....see you tomorrow hopefully.

You will get back your quiz on Newton's 1st Law (chapter 4) tomorrow. If you didn't take this before break, be prepared to take it tomorrow. No exceptions.

1) Get a sheet of lined paper for today's work. We just started to look at the second law before break. Use the net to search for simple, clear definitions of these key vocab. terms. Number #1-8.
 * directly proportional
 * inversely proportional
 * friction
 * coefficient of friction
 * fluids
 * air resistance
 * free-body diagram
 * pressure (definition should include reference to area)
 * terminal velocity

2) Click on the link below. Select and click on Newton's Second Law of Motion. Record answers to each letter. [|ThinkQuest page] a) How do the 1st and 2nd laws differ in terms of net force? b) Newton's 2nd law can be expressed with the equation Force = mass x acceleration Solve the two math questions shown. Write down the correct answers.

3) Click on the next link. [|TecherTech page] a) What does it mean to say that "everyone unconsciously knows the second law"?

4) Click on the next link. [|Zonalandeducation page] a) What does the second law state about direction? b) Use this page to get a better understanding of the proportions involved with the second law equation. Describe what you notice in the first animation showing a **changing F** and a **constant m**? c) What do you notice in the second animation showing **constant F** and a **changing m**?

5) This link is to a quiz. Click on the link and then select the underlined Concepts. (It's about six or lines down from top) [|Practice Quiz] a) There are 8 questions. Read each question, select an answer and record on your paper as well. If you get the question incorrect, select the "why" and record a brief note about the correct explanation.

6) And onto the next link... [|Pressure] a) What two quantities does pressure depend on? b) Read down through the bold section "The Difference Between Force and Pressure." Record an explanation of why force and pressure are not the same thing.

I forgot I was out for the school training session during your period today. Leave work with substitute. I will be back in my room at end of day. I will give you updated printout on Monday...promise. Have a good weekend. NOW....GET TO WORK!

1) If you owe questions #14-20 on p. 57, please complete and give to substitute.

2) If you owe the questions (A-K) from Tuesday - read below and complete. You will have to page down to get to Tuesday's heading below. Give to the substitute.

3) I have all of your graded work updated. Please check the following list. If needed, complete and give to the substitute.
 * concept page 4-1 (one about the bus and pencil)
 * concept page #4-7 (one with books on girl's head and hammer)
 * notes on Newton reading handout (if you missed the day before Thanksgiving--get it done!)

4) Several you have everything described in #1-3 complete. The rest of you should not need the entire period to do so. That means....you need to start this today!

__**New Newton Assignment**__ - With Newton's birthday coming after our winter break, I want "pairs" of you to select an aspect of his life to research and prepare a visual (poster) to be placed on one of the bulletin boards outside of our room. Either the substitute OR one of you please start make a list of the following selections on a sheet of paper. With ONE partner, select one and sign your names beside it on the paper.
 * life - youth Slavek and Jaime
 * life - time while professor at Caombridge
 * life - time as government offical
 * optics
 * mathematics
 * mechanics
 * gravitation
 * alchemy & chemistry Curtis, Sam, Leah - CANNOT have 3. You guys work it out. If you want to stay as 3, you'll have to pick another category as well.
 * chronological studies and work
 * publications Frank and Derek
 * personality / characteristics Darian, Mark, Denton - CANNOT have 3. You guys work it out. If you want to stay as 3, you'll have to pick another category too.
 * how the way he did science was different than others before him
 * relationships with other scientists

After you've made your selection from the list, **start to find information**. **Dig deeply**! **Collect your info today be either saving in your server account or paper/pencil**. DO NOT print today. Look for visual supports as well and save in your server account. We want to create an awesome bulletin board wall of Newton's life and why he should be celebrated! Think creativity. Think "out of the box."

==Go to [|The Physics Classroom] and read about Newton's 1st Law. Use a sheet of paper as you read and watch the animations to answer these questions. You do not need to write the questions, simply write each question's letter.==

A) What does the phrase "unless acted upon by an unbalanced force" mean? B) Click on the first animation. From that page, how does wearing a seat belt affect your motion in a car? Describe. C) How does not wearing a seatbelt affect your motion in a car? Describe. D) Go back one page. Select any one of the bulleted applications of Newton's 1st law. Describe how inertia applies to the example you selected. Can you describe another application of the law? Think of one on your own. Or maybe "google" for another one please. Describe this additional example. E) Click on the 2nd animation. What does the ladder become after the collision? What kind of motion? F) Below that animation click on INERTIA. What did Galileo conclude about initial and final height of ball rolling on incline? G) Newton claimed a force was not needed to keep an object in motion. What is it that is repsonsible for moving objects coming to a stop (like the sliding book)? H) How does this page describe mass? I) Read about the books on the head example - should look familiar from yesterday. Write anything you may need to help you remember this explanation. J) Quiz yourself honestly on the questions #1-7. Write anything you may need to help you recall the correct answers. (They look like good quiz questions for next week. hint-hint :) K) Click on next section:state of motion in the lower right corner. Read and answer the questions 1 and 2 in the same way. Watch the animation.

Thank you! Leave your paper with the sub. See you tomorrow.

Your Pics

[|quia] at the page that comes up select conc. of physics 2. please complete all 4 activities listed. 1 new activity has been added for you to try.

On yesterday's paper change #7: Select a sport and write it on your paper. You cannot select the same sport as anyone who is your "neighbor" in the class. You can pick anything from baseball to fencing. If you need some ideas on some lesser known sports - goggle maybe. Start to search for sites that maybe give you info on the "scienc of ?" or the "physics of". Physics is embedded deeply in sports. If I know what interests you and your classmates, I can plan lessons around those interests - starting next week. On your paper - write down your sport and the URLs of 3 websites that give us some info. If you're not sure about a site - ask me, just be patient. :)

If you have time - check out this game site. When you go to the site, you will have to enter one of these id #s to try some questions on the scientific method. [|Review Game Zone] play the game numbers 2523, 1111, 85, 692 (indep/dep variables) NOTE: I did not create these games. Each games has 1 or 2 questions we didn't cover. i
