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!!

And how does equilibrium relate to Newton’s first law? And what if you don’t have balanced forces. Aaahhh, net forces produce what?

From homework – #34, 36 – 37, 39 – 40, 46 – 47, work on a few and answers for the rest. How are you doing on them? Drawing them is HUGE, and be careful of squaring and taking the square root. Also, watch out for direction – positive and negative. Are you finding that you’re starting to be able see some light at the end of the tunnel? You’re doing a great job!

Does that ring a bell? From Monday, here are a couple of free fall problems that we worked in class. #32, the “ball dropped from the top of a building and thrown up from the ground at the same time” problem and then a few from me that I thought would help as you learn to work these. (This is the day we worked the volleyball problem.) And also perhaps help as you do the calculations in finding the height of the balcony?! :) How’d you do on that by the way? Was your percent error under 10%? Make sure you give in your conclusion reasons for any error you might have had.

Here’s the lecture from Thursday on acceleration due to gravity. Hey what’s your reaction time? And did you figure out why you can’t catch the dollar bill? Write it up as a kind of mini-lab report in your lab book. Put your data in a table and be sure and show all your calculations/work. Have a great extra long weekend!
