Today we started off class by turning in our Friction questions worksheet that was homework last night. We then talked about our test averages. After, we watched a Simpsons' clip that showed the school floor being replaced by an ice rink and had no friction. We then proceeded by taking notes over friction. Our conversation strayed away from our friction notes for a moment when Lauren shared a story about a teacher putting a folder on a student's head and using a rubber band to hold it in place so that the student could not cheat during a test. We then did an example on our example sheet together and then completed a pair check with our lab partner. Our homework tonight is pg. 128 (#34, 35, 37, 39-44).
Question of the Day: What things affect the coefficient of friction?
Answer: Smoothness, whether or not they're lubricated, magnitude of the normal force, and type of materials in contact.
