Today we began talking about free fall. Homework is to complete the graphs we started in class so we can finish our discussion tomorrow.

Today we summarized everything we have learned so far onto a single worksheet. We summarized all of our definitions, formulas, equations, and graphs so that we would have everything together to make problem solving easier. Tomorrow we will talk about free fall.
Since most groups did not complete the challenge on Friday, we completed it in class today. No new work, and no homework tonight. Make sure you handed in your group's writeup for the challenge.
3rd Period: We started to talk about motion problems involving 2 objects, but the worksheet didn't make sense (sorry!). We briefly talked about how to solve problems involving two objects, did an example, and then started a practice worksheet. Unfortunately, the practice worksheet really didn't apply to 2 object problems. The assignment was to complete the first 5 problems. Any additional problems you complete with count for extra credit.
5th & 6th period: We talked about solving problems involving 2 objects, and did an example together. Homework is from the book p. 54 #29, 31, 33, 34, 35, due tomorrow. Tomorrow we will have a physics buck challenge! The entire worksheet (McComb's acceleration) is due tomorrow. Remember, quiz on Friday.
Today we reviewed the relationship between a position time graph and a velocity time graph. Then we practiced applying our kinematics equations to constant acceleration problems. You should have the first side of your worksheet completed, as well as the first 4 problems on the back side for tomorrow. We will check answers in class and work together to complete the remaining problems.
Today you gathered position vs. time data for a marble rolling down an inclined track. You need to graph your data (make sure time is on the x-axis!!). Tomorrow you should be prepared to answer the question "What evidence do you have that the marble is/is not moving at a constant velocity?" If you did not complete the motion map practice, you should also do that tonight as we will be talking about it tomorrow.
Today we finished the motion detector lab, and then practices using the various representations of motion (graphs, motion diagrams, verbal descriptions). Tomorrow we will use the kinematics equations to solve problems.
Today we reviewed our definitions for position, displacement, and average velocity, and began applying them to problems involving constant velocity. Homework is p. 53 #1-8 (skip #3, we did it in class). Solutions to homework problems are available here.
Today you gathered position vs. time data for two different motorized cars. You should graph your data, find the lines of best fit, calculate the slope of each line, and write the equation for each line. We will be talking about the graphs tomorrow.
