Today we started discussing some of friction's properties as a force. We discovered that no matter what direction of the motion, friction will be right there to oppose it.
Tonight's homework is Thinksheet #125 which reviews yesterday's lesson on Net Force. The two people doing the pushing and pulling were originally going to be Messer and Woo Shik, but they were unavailable so you have two stand-ins instead. It's three pages long, but easier than it looks. Use your notes and common sense. It will be collected Friday and graded. Good luck!
