Now that we've developed an understanding of Newton's Laws of Motion, free body diagrams, friction, and forces on flat surfaces, we can extend these tools to situations on ramps, or inclined, surfaces. The key to understanding these situations is creating an accurate free body diagram after choosing convenient x- and y-axes.
