INVESTIGATIVE QUESTION: How precisely can we measure the coefficient of friction between a wood block and other surfaces?

  • The goal here is to practice our measuring skills.... as well as do a wee bit of research.

  • Work with your team to *derive* a method for calculating coefficient of friction using formulae we ALREADY know.

  • You WILL be comparing your experimental values against REAL WORLD c.o.f.s so you'll have to make sure that you can find those reference values BEFORE you begin.

    • Create a shared Google Sheet with all members of your lab team.
    • Have each team member research c.o.f.s for wood and various other materials. THIS IS DIFFICULT. WORK to make the biggest list you can. THEN go and see if you can find those materials here at school or bring them in to test.
  • Use that information to develop a plan for measuring the coefficient of friction for 3 different surfaces in and around our physics classroom.

 

All labs are due one week from the last day of the investigation.

You SHOULD collaborate with your group members in all aspects of the lab -- including the written report. You should NOT, however, copy and paste anything from anyone else at any time for any reason. You should NOT take work from another person or other source and put your name on it... Ever.... For Any Reason.
