Today we solved force problems together on whiteboards. The problems involved friction, tension, and pulleys. No homework this weekend. We will finish the forces unit next week and have a test on Thursday!
If you missed the pulley unit, here is a powerpoint that takes you through calculating the mechanical advantage of a hauling system. If you play the ppt in presentation mode, it will take you through the process step by step.
