Today we reviewed for the exam, which has been moved to Thursday! The solutions to the practice test are available in the google drive folder.

Today we learned how to find the velocity(as a function of time) for an object that has drag acting on it. This involves writing and solving a first order differential equation. You have 4 practice problems on a worksheet. The solutions to the practice problems are in the google drive folder. Do not panic if you are not able to understand how to use calculus to solve these problems at this moment in time! This topic may appear on the test, however, it will not be a major portion of the test. For some of you who are just beginning to learn calculus, these types of problems may be confusing right now. As you increase your calculus knowledge and your physics knowledge, they will get easier.
Today we talked about Drag and terminal velocity. Wednesday you are doing a lab on terminal velocity.
The unit 2 test retake free response solutions are available here.
The multiple choice answer are: 1. A 2. A 3. D 4. D 5. C 6. E 7. D 8. E 9. C 10. B 11. A 12. D 13. C 14. E 15. D 16. D 17. C 18. B 19. C 20. E 21. B 22. C 23. D 24. B 25. D Today we finished working some friction problems together, then you started a new webassign assignment. The friction lab is due next Wednesday 11/23.
Today we worked on friction problems and/or finishing up the lab writeup. We did not cover any new material since many students were missing due to the AP Euro field trip and Interhigh meeting. Please work on the webassign problems, and come see me for help if you are struggling!
Yesterday we began a lab in which you are experimentally gathering data to determine the coefficient of static friction and the coefficient of kinetic friction between 2 surfaces. You will also determine whether mass or surface area affect the coefficient of friction. We will complete the data gathering portion of the lab today. The completed lab is due next Monday (11/21). Make sure you answer the lab questions thoroughly and use free body diagrams to illustrate your answers.
The retake for the unit 2 test (covering vectors, 2 dimensional kinematics, relative motion, uniform circular motion, and non-uniform circular motion) is on Monday 11/14 either before school (arrive by 6:30 to finish by 7:30) or after school (start at 2:30 to finish by 3:30). In order to be eligible for the retest, you must have handed in your test corrections (they were due last Monday 11/7), and you must have complete all the webassign homework for the unit (vectors, projectiles #1, projectiles #2, relative motion, uniform circular motion, non-uniform circular motion).
Today we talked about mass and weight; we learned how to calculate the gravitational force between two objects using Newton's law of universal gravitation, and we began talking about friction. There is a webassign problem set that covers these concepts. You should begin working on these problems, even though you may not be able to solve all of the friction problems yet.
Today we did a recap of forces for motion in a straight line. We then practiced problems related to these concepts. Make sure you do the latest webassign problem set.

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!
