Today we reviewed a bit for our test on Thursday. Keep working on your mastering physics assignments, read the chapter (ch 2 in the Knight book), and come to class on Wednesday with any questions you still have!

Today we talked about free fall, and we practiced solving some problems together.
PLEASE make sure you are working on the homework (masteringphysics.com). Also, read the online textbook - we are in chapter 2. The book is really good and will help you if you are struggling!! Today we practiced solving kinematics problems. The solutions to the packet of graphing questions is available in google drive. Check to see how you did and hand in your packet tomorrow for credit.
PLEASE make sure you are working on the homework. Since we did not get to free fall today, DO NOT START the free fall problems yet. Also, read the online textbook - we are in chapter 2. The book is really go and will help you if you are struggling!! Today we registered our Mastering Physics accounts. You can now begin your online homework! We also completed a lab where you set up a ramp and a smartcart so that the smartcart moved to match the given graph.
Today we learned how to use motion diagrams, and also looked at position, velocity, and acceleration graphs. We worked through some graph examples, and began to look at practice problems as well (Solutions to the practice problems available here). Keep working on the homework - I finally have the access codes for MasteringPhysics, so we will set up your accounts during the block period.
Today we finished deriving the kinematics equations, and began using them to solve problems (slides are at the end of yesterday's PPT). Good practice problems include #17, 20-22, 25-27, 29-37. Don't attempt to do them all in one sitting!! Solutions are available in the google drive folder.
Today we looked at our position vs. time graph for the marble lab and discussed the concepts of average velocity and instantaneous velocity. We talked about position, velocity, and acceleration graphs, and began to derive the kinematics equations.
Drawing Tangent Lines video (Youtube) Today you gathered data for a marble rolling down an incline. For Thursday you should have a sketch of your experimental setup, data tables, and a beautiful position vs. time graph. **IMPORTANT** For your graph, draw the x-axis along the LONG side of the paper and put TIME on the x-axis. Make your graphs BIG. Like, use the whole page. Really.
Today we finished defining terms: scalar, vector, position, displacement, distance, speed, velocity and began solving uniform motion problems. I passed out some practice problems on a worksheet. Make sure you take a look at #5-16. Do as many of them as you need to make sure you understand the concepts (includes position vs time graphs, velocity vs. time graphs, displacement, distance, speed, velocity problems. Solutions to #5-16 are available here if you want to check your work.
Today we reviewed position vs. time and velocity vs. time graphs, how they relate the each other, and several definitions (see yesterday's PPT). We practiced interpreting graphs, and going from a description to a graph.

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!
