Today we talked about forces, Newton's First law, and Free Body Diagrams. Homework is a packet to practice drawing free body diagrams. I will be collecting the packet tomorrow.

There are a lot of questions about how the bullseye lab was graded, and why the grades were so low. Take a look at the original lab requirements, then use the grading rubric to score your lab report. If you feel that I cheated you out of points, we can look at your lab and the rubric together and adjust your points accordingly. Here are two labs that were well done: Lab 1 and Lab 2.
Nice job on the exams. The second free response seemed to cause the most pain! Work on test corrections on Friday. Test corrections are due next Friday, November 3rd. Remember, if you want to do a retest, you need to have each webassign assignment (for the chapter) completed to 75%.
MC Answer Keys (scroll to find your version) Free response Solutions Version A/B Free response Solutions Version C/D Tomorrow is our test on motion in 2 dimensions. You should be familiar with trig, finding components of vectors, adding vectors using components, projectile motion, and relative motion.
You should have plenty of practice problems to keep you busy! There are problems on webassign, as well as a packet that I handed out. The solutions to the problems in the packet are in google drive or click here:
Projectile Motion Solutions Relative Motion Solutions Thursday and Friday we will be practicing problem solving. We have finished the material for this unit, the test will be next Wednesday (most likely). If you are doing the webassign RETEST, it needs to be completed by 10 pm Monday 10/23.
Today we talked about relative velocity. This is section 3.4 (p. 74-77) in your book. Here is a good video from A Plus Physics that covers relative velocity.
We spent today completing the bulls eye lab data collection and challenge problem. Remember, your lab writeup is due on Friday, and late work will incur a 10% penalty.
Today you wrote a procedure and gathered data to allow you to predict where a marble will land when it rolls off of the lab table. The lab report is due Friday 10/20. There will be a 10% penalty for labs that are handed in late.
Today we worked through several example problems together. Solutions to all of the examples are available in google drive.
Video solution for problems #29 and #31 in your book (Chapter 3). |
Reminders:
Chapter 2 test retake is Wednesday 10/17. You can take the retest either before school or after school, but you must complete all of the Chapter 2 homework (75% completion on each assignment) to be eligible for a retake!
