1. Do Now – 5 Minutes Topic – Friction Lab We are going to try something new here: You may select your own lab partners I want guys to only work with guys I want girls to only work with girls Please read over the lab manual with your group-mates.

2. Homework Friction Lab – Due Monday, 12/15 Newton’s 2 nd Law Worksheet (4 Days Late) Test Corrections – (4 Days Late)

3. Upcoming Test Our next big test is going to be on Wednesday, December 17 th. Topics will include: Newton’s 1 st Law Newton’s 2 nd Law Newton’s 3 rd Law Friction Hooke’s Law Expect there to be problems involving kinematic equations

4. Friction Lab The batteries on the Xplorers may not have any juice in them, so they will need to be plugged in. Your coefficient of friction SHOULD be between 0 and 1. Ignore the negative sign your Xplorer gives you

5. Friction Lab Change to Question 3: …static friction. Based on the procedure you performed in this lab, would it have been possible to determine the coefficient of kinetic friction? Explain by citing your graph.
