5: T 10/17, 7: T 10/17 Today, we'll collaborate to make sure you have all necessary data and graphs to discover the mathematical relationship between force, mass, and motion. We'll make sure that you are able to take the first step in analyzing data  use the Logger Pro data to form two graphs that summarize the relationships found in each of the two experiments. Remember, finding the relationships means finding an equation that relates the two variables. We'll review how to linearize graphs if necessary. I will have the laptop cart so that you can continue to add to your lab report. If you need to redo any trials, you can do it during this period.
Homework: Continue working on your lab writeup:  If you have not already, write an introduction that states the purpose of the lab. It should include a discussion of the 6 possible experiments you could have done and which two you chose to do and why.
 Include one one of your x vs. t graphs and one of your v vs. t graphs in your report before your data tables. Discuss in the report what you noticed about each of the graph that informed you about the motion of the cart.
 Create and include the two final graphs: one that summarize each of the experiments. Describe the relationship you see in words. Additionally, if either of the graphs is not linear, you must transform the graph. (If you need help in transforming graphs, refer to this worksheet that you were supposed to do a couple weeks ago: determining relationships from graphs.) Explain what you did and why. Find an equation for each experiment that describes the relationship between the independent and dependent variables.
 Make sure that you have your constant variables written down somewhere (system mass in one experiment and pulling mass in the other experiment).
