Today we talked about the concept of relative motion. There is a new assignment on Mastering Physics to practice relative motion.
Here are some videos to help you if you were absent: A Plus Physics: Relative Motion Twu Physics (videos 23-25) Remember your lab is due tomorrow at the end of the period. Today we did the bullseye lab. The lab writeup is due by Friday.
Other things you should have completed and handed in (if not, get them in by Friday): Projectile Motion Online Lab Notes & Example Problems on Projectile Motion Quiz Corrections - you can earn back half the points you missed by doing quiz corrections. On a separate sheet of paper, rework the problem and make sure you show all of your work and give a quick explanation of what you did wrong on the original quiz. Quiz corrections are due Friday 10/26. NO LATE WORK ACCEPTED! Also, make sure you are working on the Mastering Physics Homework!! Today we discussed the results of the projectile motion lab, and began solving projectile motion problems. The solutions to the problems we worked together are here. Please finish the ranking task questions at the end of the packet. The online lab and packet are due on Monday. On Thursday and Friday you will have a sub.
Thursday is a workday to work on online homework, the packet, or your lab. Helpful videos: A Plus Physics - projectile motion horizontal projectiles angled projectiles Twu physics - projectile motion- there are several videos on this page! Friday you will have a quiz on vectors. SOlutions to the vector addition warmup questions are here. Vector addition video (twu physics). Today we worked on an online projectile investigation. Please have the investigation completed by tomorrow so we can discuss the conclusions in class!
Today we learned how to add vectors using components. Make sure you practice this skill by doing the homework this weekend!
If you are struggling with the graphical vector problems on Mastering Physics, here are some hints on how to use it (I am still learning, too!). You cannot move the vectors that were given in the problem. You can add unlabeled vectors to the canvas. Use unlabeled vectors to do the addition/subtraction/scalar multiplication. Once you have the graphical addition set up with unlabeled vectors, you can add a labeled vector for the vector that you were trying to find. Today we started working with vectors in two dimensions. We talked about using trigonometry to decompose a vector into x and y components, we talked about polar form, component form, and unit vector notation. We began to add vectors graphically. You should begin working on the Mastering Physics assignment for vectors. NO QUIZ TOMORROW.
Your test has been scored on an AP scale. In order to keep your scaled score, you must do test corrections. The guidelines for test corrections can be found here. Do your test corrections on a separate sheet of paper, and staple them to your original test. Test corrections are due next Tuesday 10/9. The solutions to the test are also found in the google drive folder - Solutions for versions A/D and solutions for version B/C.
MC Answer Key available here. Scroll down to find the correct version. Many of us are still struggling with concepts and vocabulary and need a few more days to practice putting everything together. The test will be on Monday 10/1. Things that you can do to get ready for the test:
Today we did a challenging free fall problem (gumby - solution on 3rd page). . We also talked about how to use integrals (area under a curve) to go from acceleration to velocity, or velocity to position. Please try the integral problems on the back of the worksheet for thursday (solutions here). The test has been moved to Monday!

REMINDERs:Chapter 2 test retake is Monday 10/15. 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!
Resources:Review videos - excellent videos covering all AP Physics C content.
