Physics 11-20-09 TEST CHANGE!!

Ms. Skinner — Sat, 21 Nov 2009 02:53:14 +0000

PHYSICS: Well, the more I thought about it, the more realized it just wouldn’t be a good idea to have the test either Monday or Tuesday. I hate to move it to after Thanksgiving, but I think it would be best. We’ll finish correcting the chapter 4 problems and finish the lab on Monday, practice all problem solving on Tuesday, review the Monday after Thanksgiving, and take the test on that Tuesday – December 1. Let me know if you have questions or concerns about this.

Here’s the very brief vodcast from Friday – just a tiny bit of review. I think I went over the answers on the pg. 190-191 review problems, and we also started brainstorming on how to work #17 on pg. 191. See if you can work it now yourself. Have a great weekend!!

Physics 11-13-09 Conservation of Energy Problems Review – 2

Ms. Skinner — Sat, 14 Nov 2009 02:10:20 +0000

PHYSICS: Here’s one last review of the conservation of energy and work-energy theorem problems. We did the Tarzan problem and a few sliding up and down inclines (the problems, I mean, not us!) – #40, 41, 46, 48, I think. Good job on them! We’ll do power on Monday. Have a great weekend!

Physics 11-5-09 Work Energy Theorem

Ms. Skinner — Fri, 06 Nov 2009 03:40:14 +0000

PHYSICS: Great job on the problems today – good connections between work and energy. I think you’ll like using the work-energy theorem, it’ll save you some time and a couple of steps. Don’t forget about friction!

Physics 11-4-09 Intro to Work

Ms. Skinner — Thu, 05 Nov 2009 03:33:44 +0000

PHYSICS: Funny thing about words, all this work you thought you’d been doing, was it? Work, I mean? Great intro to chapter 5! Josh, I think you almost did move the lab station! I think you’ll all do great with the work problems, just remember everything from the last chapter and multiply by d!

Physics 10-29-09 Chapter 4 Test Review

Ms. Skinner — Fri, 30 Oct 2009 00:54:39 +0000

PHYSICS: I’m so proud of you – you’re doing a great job on thinking through these problems! Good luck in studying for your test. Practice, practice practice the problems, but don’t forget the conceptual stuff. If you get a chance, watch the Julius Sumner Miller videos on Newton’s laws in the Vodpod below, or look them up on You Tube. I think they’ll help a lot with the conceptual information. Help session in the morning at 7:15 A.M., if you need extra help. I’ll be praying for you!
