5/8 Physics update and homework due 5/15
Hi folks,
This week we spent a large amount of time taking another look at ray diagrams. Last week's quiz was difficult for most folks so I took the time this week do more with lenses, mirrors and ray diagrams.
We also took a small dip into the world of static electricity. We will do a bit more with that next week.
Next week is our last week to meet other than the final and I'd like to allow time for questions and review. For homework this week, please spend time looking over your old quizzes. Bring any questions you may have to class next week for us all to take a look at. Remember, there are no dumb questions. If you feel uncertain about something, it's almost guaranteed someone else in class has the same issue…and they may not even know it.
Also for homework, take a look at that data table you made this week and see if you can make any patterns out of it. We'll discuss that further next week.
Feel free to email me if you need some help as well.
See you all next week.

Physics Final exam on May 22
Hi folks,
Just a reminder that we have two more classes and then the final exam.
To prepare for the final, I would highly recommend taking a look at all your old quizzes. The final exam will be based on the same material those quizzes were based on. Be sure to go over all questions that you may have missed and be sure to understand them so that you'll be ready for the exam. If you have trouble understanding where you went wrong, there's a good chance the material was covered in a recording and you can also email me if you need help. Feel free to ask questions at the beginning or end of class as well.
I'll provide all formulas and constants so you will not need to worry about memorizing anything.
Good luck everyone!
Never Stop Wondering,

Update on Physics Class this week
Hi folks,
I'll email tomorrow with a confirmation, however, my wife reminded me that we may not have power tomorrow if the ice storm is as bad as it's supposed to be. If you DO NOT hear from me tomorrow please assume that I have no power and as such I am probably not traveling either.
Again, just to clarify, if you do not hear from me, there will be no class tomorrow.
Off to fill some water jugs. :)
Be safe every one.

2/6 Physics update and homework due 2/13
Hi folks,
Today we continued our investigation into simple machines and their relation to work. We did some work with pulleys and discovered the inverse relationship between distance and force.
For homework this week:
Read the pulley chapter in the book.
Take a look at the enclosed .pdf and do all the questions at the end.
Also, answer the following questions.
1. With the pulleys, how did work out relate to work in?
2. With the levers, did work out relate to work in? It should have. So what wasn't measured that caused work out to not relate to work in in the same way as the pulleys?
3. What relationship did force have in regards to distance as you worked with the pulleys?
4. As you increased the number of pulleys, what effect did that have on the effort force? What effect did it have on the effort distance?
5. a. If you were lifting a load that required a force of 10N with one pulley, what effort force would be required?
b. Same question, but now you're using 2 pulleys?
c. How about 10 pulleys?
6. a. If you were lifting that load 1 meter, what would the work in distance be for one pulley?
b. 2 pulleys?
c. 10 pulleys?

1/30 physics update and homework due 2/6
Hi folks,
Today we talked about about human energy and how humans get and use energy in the form of calories.
We also did a bit of work with simple machines and did a lab using the lever.
Homework this week is to answer the questions in this email and
Read the Levers chapter in the Bite-Size Physics book I sent and do all 5 questions at the end of the chapter. Please use the answers as reference only! Answer them yourself first. :)
Create the graph we talked about in class and using that graph answer the following questions.
1. What happened to the effort force as the fulcrum got closer to the load?
2. What happened to the effort force as the fulcrum got farther from the load?
3. What happened to the load force as the fulcrum got closer to the load?
4. How about when the fulcrum got farther from the load?
5. If you wanted to lift an object that you couldn't lift by yourself, where would you put the fulcrum? Close to, or far from the load?
6. What relationship does distance have to force in regards to the lever?

1/23 physics update and homework due 1/30
Hi folks,
Last week we did a nice conceptual overview of what energy is and this week we got a bit more into the nitty gritty and mathematics behind energy. We introduced the concept that energy is the ability to do work and that work is equal to force times distance. We also talked about power which is the rate at which work is done.
In my opinion the text that we're using goes into too little detail on energy. I'm including my Energy eBook to help supplement the text
Homework for due 1/30 is to
Read pp 103 and 104
Read the Energy and Work chapter in the eBook
Do Review Questions on page 119 #'s 1 - 5
Plug and Chug Pg 120 #'s 1 and 3
Think and Solve # 2, 4
Also, do the "Find the Power" experiment in the eBook. We did the first part where you find your wattage in class. (Email me if you can't remember your wattage.) Compare yourself to at least 5 different appliances.

Recording of Week 17 class: Introduction to Energy
Your video's now on YouTube.

1/16 Physics update and homework due 1/23
Hi folks,
We have started our energy block today. We discussed how we perceive energy using our energy "antennae", our ears, eyes and skin. We also discussed how energy is like a phantom. It's invisible until it interacts with matter, it changes forms and it can neither be created nor destroyed.
Homework for this week is to do the enclosed .pdf. This is another exercise with a PHET simulation. There still seems to be some confusion with conservation of momentum so this well help to nail down that concept. Besides….it's kinda fun! :)

1/9 physics update and homework due 1/16
Hi folks,
Today we wrapped up our unit on mechanics with a lab practicum. The students used all their new and fun formulas to analyze the game Angry Birds. They figured out the momentum, mass, force, impulse, acceleration, velocity and more of various aspects of the game. If you would like to get into this in even more depth a fellow by the name of Rhett Allain has done many many calculations on various parts of the game. Here is a link to a forum with bunches of articles by him.
Homework for this week is to:
Read Chapter 11 pgs. 150 - 164
Do the ODD Review Questions on page 165 #'s 1-19
Do Plug and Chug Questions #'s 1 and 2
10 points of extra credit if you do the first activity on page 166.
