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

http://www.youtube.com/watch?v=a15uuMu_Ra4

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.

Week 13 Physics Recording - Newton's 3rd Law

12/3 Physics update and homework due 12/10

Hi folks,

A fun day today as we pushed Ben's car in the parking lot to show Newton's 2nd law by seeing the affect of our force on the mass of the car (thank you Ben). We also investigated Newton's 3rd law by looking at what happened when we added mass to Matchbox cars that were being repelled by magnets.

Homework this week is to:

Read the text book pgs 59 - 70.

At the end of the chapter, do the odd numbered review questions 1-18

At the end of the chapter do the Plug and Chug questions #'s 1-5
