1/7 Physics update and homework due 1/14

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 finish up the lab work at home.  Some of the questions are quite tough, so please feel free to email me if hints are needed.

There will be no recording this week since most of the class consisted of the lab practicum.

Physics Class resumes this week.

Hi folks,

Just a reminder for all that physics restarts this coming week. Hope everyone had a wonderful set of holidays and is all set for a brand new year!

Also, if you happen to have any device with the game Angry Birds on it, please bring it to class. We are going to do a lab practicum this week where we will be applying concepts we've learned in the mechanics block to analyze different aspects of the game.

Lastly, if anyone that is missing assignments would like to know what assignments they are missing, please let me know. I'll be happy to get you that information so that you can get credit for those assignments.

See you all soon.

Class photos

Hi folks,

Madison's mom took some fun photos at the end of class last week.  I thought you might get a kick out of seeing them.

Happy Holidays!

Jim

Week 15 Physics Recording: Momentum transfer, conservation and impulse

12/17 Physics Class update and homework due 1/7

Hi folks,

Lots of work today. For the first part of class, we focused on the concepts of conservation of momentum and transfer of momentum. We also got very mathy as we took a look at problems dealing with conservation and transfer of momentum.

After that, we took a look at the concept of impulse. Impulse is what makes momentum happen. It is the hit/kick/punch/push/etc. that changes the momentum of something. To explore this concept, we did a very complicated and serious lab where we went outside and shot spitballs. This brought us to my favorite equation ft = change in momentum. This is my favorite equation because it is the reason seat belts and airbags keep you safe in a car. Basically, the slower one's momentum changes the less force there is to do damage.


Homework:

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.)

12/10 physics update and homework due 12/17

Hi folks,

Today we spent a bit more time with Newton's 3rd Law and also introduced the concept of momentum. We did a lab today looking at the effect mass and velocity have on momentum.

Homework due 12/16 is:

Read pages 74 - 82 in the text book.

Do Review Questions #'s 1 - 17

Also, take some time and take pictures or shoot videos of 2 examples of each one of Newton's Laws. So 6 pictures in all. I don't want you to necessarily set up the pictures, just find things that are examples of each one of the laws. Have fun with this! Feel free to email me the pictures or you can print them out and hand them in if you wish.
