Physics - Unit 4: The Balanced Force Particle Model

This unit is an investigation of systems with a constant velocity.You should be reading Chapters 4 and 5, but be aware that we will not do force problems with acceleration until Unit 5.A paper on Free-Body (or Force) diagrams and an example of an "Interaction Diagram" or "System Schema" are below. Also, there are diagrams of the system idea in page 89 in the text.
