## Friday, December 10, 2010

### Test coming up! Time to study!

Test next week!

Period 2, 7 - Tuesday
Period 3, 5, 6 - Wednesday

You will be provided with a list of the equations.

You should be reviewing Packets 3 (Forces), 4 (Momentum), and 5 (Work and Energy)
Try each of the problems again without looking at the solutions. Then check your answers and use the solutions to help you if you didn't get it correct.

Some sites to go to for review:
Forces: http://www.physicsclassroom.com/Class/newtlaws/
Momentum: http://www.physicsclassroom.com/Class/momentum/
Work and Energy: http://www.physicsclassroom.com/Class/energy/

Come in to class on Monday with any questions you may have on these topics. I will answer questions, but I will not just do a "review".

### Student Access to Power School

Students now have access to PowerSchool. You can check your grades and attendance very easily. If your teacher uses the Gradebook (like I do) you can see individual grades and even check if you are missing any work.

Login is done just like you are logging into a school computer.

Here is the link:
https://powerschool.bridgeportedu.net/public/home.html

Make sure you also check to see if there are any "CUTS" that should be "EAB" (excused absence) and get a note from your parent or have your parent call the school.

### Algebra Help

Since I know many of you struggle with algebra (not necessarily your fault either!) I thought I'd post some resources to help you.

http://www.algebrahelp.com/ is a great site that has mini lessons for you to learn more about different parts of algebra. It is broken down by topic.

http://bridgeportmath.org/ - site for the math department for Bridgeport. It has some great information and resources for you to review and reinforce math concepts.

http://www.physicsphenomena.com/PhysicsMathReview.htm - Physics math review - great resource for help with math in physics.

http://www.physicsclassroom.com/ - has some problem solving help in each section that will help you with some of the algebra.

And of course you can always ask me for help. Do not hesitate to come after school or email me for help. Do not wait until it is too late.

### Work and Energy LAB

For the Work and Energy LAB (Discovery Lab - Exploring Work and Energy) that we are doing this week, you must write a full lab report.

Each student must write their own lab report. Do not copy from your partners. Any labs that appear copied will share the full grade (in other words, if 3 people copy from each other, the highest grade any of them can get is a 33/100).

Here are the lab report guidelines (which were also handed out during class)

Remember: Labs are performed in groups for data collection purposes only. Your lab report should NOT be the result of shared writing, copying, or cooperative effort. This includes your calculations. You must do this on your own. Remember to cite any references you use and do not copy from the lab sheets into your lab report. GRAPHS MUST be done on your own—make your own title, labels, etc.  If the identical graph is turned in for multiple people, none of the individuals will receive credit for the graph portion of the analysis!
1. TITLE and DATE, NAME, CLASS PERIOD

2. INTRODUCTION-- The introduction must clearly state the objectives of the lab. It should also include background information on the topic that the lab is about.

3. PROCEDURE--First list ALL lab equipment used in performing the lab. Draw a sketch of the lab setup and label all equipment used. Then list numerically the steps used in completing the gathering of the data required for the lab. Be sure to mention how many trials were taken in the lab.

4. DATA-- Clearly list and label all raw data taken in the lab. Use a table or some other such method for presenting measurements. Make sure units are clearly labeled for all measurements.

5. CALCULATIONS-- Briefly explain what quantity is being calculated and why. Then show all formulas needed, including algebraic manipulations of standard equations where necessary. Then show the calculations for each trial. In this section also include all graphs and charts when required. This section will also contain the error calculation when required.

6. ANALYSIS-- Here, in a single section, ALL questions posed throughout the lab should be answered in order. Answer questions in full sentences and ALWAYS give reasons for Yes or No answers. If the question posed requires a calculated answer, be sure to show all standard equations along with working equations, inserted values and final answer. Show your work. This section will also contain an error analysis.

7. CONCLUSION-- In one paragraph each, explain which of the objectives were met in this lab and why, and which objectives failed to be met and why. In another paragraph describe how the lab could be improved by modifying the procedure or analysis.

8. APPENDIX—attach any lab sheets or notes used during the lab.

Hand written labs and graphs are allowed, but not recommended. If hand written, they must be neat and legible and in ink. Students should use word processing software (like Microsoft Word or Google Docs) to create the lab report. Software, such as Excel or Google Docs, should also be used to create graphs.  If needed the graphs can be hand drawn.

### Monday, November 15th

Today we are continuing Work and Energy.

So far, you have already learned and are able to:

§ calculate work done by a force, kinetic energy and gravitational potential energy;

§ explain that work done against friction is dissipated to the surroundings;

§ describe energy conversions and the conservation of energy.

Objectives:

Having completed this lesson, students should be able to:

- calculate the work done by a constant force in situations including those where the force is not in the same direction as the displacement;

- explain how the work done by a force is related to energy conversions and energy conservation;

- apply the principle of conservation of energy to simple examples (e.g. the motion of a load on a slope and the motion of a roller coaster car);

- use the equation for kinetic energy: KE = ½mv2;

- use the equation for gravitational potential energy changes: PE­­g = mgÎ”h.

Method: you will go to the computers as a group.

Log in and go to Multimedia Science School.

Select the following:

Physics

Mechanics

Work and Energy

Lesson

Energy Transformations

As you go through the lesson, make sure you pay attention to each part of the lesson and take notes. Write down any questions (and answers) and information from each page in your notes that you think is helpful for future reference. I will be checking your notes at the end of the lesson. Do not write everything down.

Take notes of important and helpful information.

Try each simulation multiple times with different variables so you can truly see what is happening.

As you work through the lessons, perform the calculations for yourselves before selecting the final row in the ‘Calculate work’ table, to check your answers.

### Physics Quest

Today you will do a Physics Web Quest to find information about Newton's Laws.

NEWTON’S LAWS OF MOTION AND FORCES

INTRODUCTION

Problems in physics will seldom look the same. Instead of solving problems by copying or by reproducing a previously solved problem, you should utilize your conceptual understanding of Newton's laws to work towards solutions to problems.

In this investigation you will gain a deeper understanding of the concept of net force that will help you solve the various problems assigned.

As you read each section on the websites, make sure you go through the practice problems and each demonstration and simulation.

TASK

By the end of this PhysicsQuest you will gain an understanding of weight, mass and net force (vector sum of all the forces) and Newton’s Three Laws of Motion.

PROCESS AND RESOURCES

You will be given a series of questions and various links to Internet sites that will help you answer the questions.

As you read each section on the websites, make sure you go through the practice problems and each demonstration and simulation

NEWTON’S FIRST LAW

What is Newton’s First Law?

What is meant by Inertia?

FORCES

A variety of force types were placed into two broad category headings on the basis of whether

the force resulted from the contact or non-contact of the two interacting objects.

Define and give an example of each contact forces using your own words. (Frictional Force, Tensional Force, Normal Force, Air Resistance Force, Applied Force and Spring Force).

NEWTON'S SECOND LAW

What is Newton’s Second Law?

What is the formula for Newton’s Second Law?

Finding Acceleration

The process of determining the acceleration of an object demands that the mass and the net force are known.

Which equation should be used to solve for acceleration?

NEWTON'S SECOND LAW

Find individual forces.

Write the three major equations used in this section:

The equation for net force,

The equation for gravitational force and

The equation for frictional force.

FREE FALL AND AIR RESISTANCE

The objective of this section is to understand how air resistance works.

Read this section and using your own words answer these questions:

What are the two factors (among others) that affect air resistance?

Why do objects which encounter air resistance ultimately reach a terminal velocity?

Why do more massive objects fall faster than less massive objects?

When you get to the bottom of the page, click the blue "NEXT" arrow and go to the next page. (follow Newton's laws of motion. There are four pages.)

Make sure you understand all three of Newton's laws. During the next class, we will be applying them and using them to solve problems. I may even ask a group to come up front and discuss one of the laws in front of the class, so be prepared!

Write up anything you learned from the NASA site that you didn’t learn from the earlier sites along with the answers to all the questions above.

You will turn in your answers as a group. You can do the work in Microsoft Word and submit it

to me electronically through this site. Make sure all group member names are on the paper.

(submit it using the tool on the right side of the site:

Good luck and have fun!

Next class we will go over what you have learned and then apply it to different problems and situations.

## Friday, September 3, 2010

### Period 6 and 7

We went over the review sheet today and started 1D motion.

Your homework:

Carl Lewis once ran 100m in 9.92s.

What was his average speed during that run?

How much distance did he cover per second, on average?

How did this relate to his top speed?
