Today you wrote your first UNIT TEST.
Today we discussed the answers for the Friction Worksheet.
I handed out a sheet called Practicing F=ma Diagrams. This summarizes all the cases you will encounter with F=ma problems.
We worked through a series of video clips that showed how to apply the F=ma equation to a variety of situations.
Here is a link to the videos:
