Free Body Diagrams and Newton's Laws

The purpose of this exercise is for you to use free-body diagrams and Newton's laws to understand forces and motion.  As you open each page, you may need to click on a link to load an animation and then push the "play" button to start the animation.  You can click on graphs to read values off of them and if you get a good graph, you can right-click on the graph and then re-size it to look at it more closely.
