comfort, dress, stupid furry boots, etc) or you can keep it all the same. It is up to your group to decide. Work to ensure the most exact data possible. Think about what will give you the best possible data. Requirements Since you will be doing this entire lab outside of class, your group will have to verify that all of you participated in the data collection or analysis. Prior to going to a store to complete the lab, your group should construct the data table which will be used to gather data. You are to include a picture of the store name where you went to do the lab. Once at the store, your group must get a signature of either the manager or someone at the customer service desk on the page containing your data table. This will signify that you have permission to conduct the experiment at the store. Failure to receive the signature will result in a zero for this lab. Also each group is to take pictures of each set of shoes (of 3 different sizes) such as 3 Nikes, 3 Addidas and 3 (ugh) Uggs. After you have gathered all of the data, create a single graph with each type of shoe that will BEST show whether or not surface area influences static friction. Be sure to label the graph with all of the appropriate details. All of your observations, data, and conclusions including answers to the post lab questions should be typed up in a paragraph or two. Make sure that your conclusions align with the data and consult the table below to see how points will be distributed. Post Lab Questions 1. Based on your results do you think that the coefficient of friction varies with the (surface) area of contact between two surfaces? 2. How could you determine (experimentally & numerically) if the surface area of an object affects the friction between it and a given surface? Write a detailed explanation on how you would test this in a lab. Points Signature 0 points No signature is -20 points. Data Table 4 points Pictures of Shoes 3 points Need at least 9 shoes total. (less than 9 shoes = -20 points) Graph 5 points
