Hi folks,
Yes…you read that right. Please try to bring some sort of a device to our next physics class that has the basic Angry Birds game on it. I know it's free on Google Play and I hope it's free on iTunes as well. We will be analyzing the birds for our next lab in class.
Happy New Year everyone!!! See you all next year.

Physics update 12/17 and homework due 1/7
Hi folks,
I hope everyone is having a nice holiday break so far.
Last class we took a good long look at one of the more important laws in science, the law of conservation of momentum. We did a couple of rather mathy problems in class and then had fun crashing balls into other balls to see the law of conservation in action.
Homework is:
Read Chapter 7 pgs. 86 to 99
Review questions #'s 1 - 9 Pg. 100
Plug and Chug questions #'s 1 - 4 Pg 101
Extra credit possibility. 2 pts for each think and solve on pg 102 (Sorry, not much fun I'm afraid.)

Clarification on physics photography assignment
Hi folks,
Some folks have already turned this in but there does seem to be some confusion on the picture assignment.
What I'm looking for is 5 pictures for Newton's first law, 5 pictures for Newtons 2nd and 5 pictures for Newton's 3rd law. 15 pictures in all.
If you would rather do videos, you can do 3 of each, so 9 videos.
I want the pictures to be something you just observe around you. An example of something that happens regularly that just happens to be a great example of one of Newton's Laws. You can set up the photo if you want to, but just give me examples of things that happen normally.
Also, with each picture, I'd like an example for why that picture is a good example of that law. I would like each picture or video to be a different example. So, in other words, you can't just use a sleeping cat over and over again. :)
The goal of this assignment is to help you guys see that Newton's laws are around you constantly if you keep your eyes open.
You can email me the pics and explanations or print them and bring them to class as well.

12/10 Physics update and homework due 12/17
Hi folks,
Today we discussed the concept of momentum. We just scratched the surface today and will be getting into it in much greater detail next week. We also did a lab to see the effect of mass and velocity on momentum.
Homework for this week is to do the following questions.
1. What is momentum?
2. Why is momentum different from inertia?
3. Which has a greater mass, a heavy truck at rest or a moving skateboard?
4. Which has more momentum, a heavy truck at rest or a moving skateboard?
5. In the lab during the last class, what did you have to do to figure out the velocity of the ball at the end of the ramp?
6. What would have changed about the experiment if you increased the amount of mass of the car instead of the ball?
7. What did changing the slope of the ramp have to do with momentum?
8. If you rolled a ball down the ramp that didn't move the car, what was greater, the momentum of the ball or the inertia of the car?
9. Draw an acceleration graph of the ball on the smaller slope (assume it reaches a terminal velocity).
10. Draw a free body diagram (force diagram) of the car after the ball has struck it but before it has stopped. (Be careful, describe the forces not the motion.)
11. Describe what Newton's 3rd law has to do with the car/ball collision.
12. Describe how Newton's 2nd law applies to the car/ball collision.
13. Describe how Newton's 1st law applies to the car/ball collision.
14. If you had appropriate equipment, how could you go about measuring and calculating the acceleration of the car?

12/3 Physics update and homework due 12/10
Hi folks,
Today we took a bit of an overview of all of Newton's three laws using a segment from at Magic School Bus video. The video has the kids frolicking on a frictionless baseball field and this allows the students to see Newton's laws in a non-friction environment.
We also did a lab using matchbox cars and magnets to illustrate some of the finer points of Newton's 3rd Law.
Homework for this week is to do Think and Explain questions 1-13 on pages 84 and 85 of the book.
Also, take 5 photo examples of each of the 3 Newton's laws. So 15 in all. Or, if you wish, make 3 videos of each law, so 9 in all. Feel free to email them to me, post them to YouTube or bring them to me somehow next week.
