There is a distinction between forces, which are pushes and pulls on an object, and free-body diagrams, which show forces acting on an object. Discover more about what free-body force diagrams are, and examine key forces and rules for free-body diagrams. What Are Free-Body Force Diagrams...
This chapter introduces the most important practice in the analysis of systems in classical mechanics: The use of the free body diagram. It provides a list (with an associated study of the physics) of the types of macroscopic everyday mechanical forces that we encounter with free body diagram ...

(Such diagrams are known as free-body diagrams and are discussedlater in this lesson.) Furthermore, because forces are vectors, the effect of an individual force upon an object is often canceled by the effect of another force. For example, the effect of a 20-Newton upward force acting ...
2. Free-body diagrams for four situations are shown below. The net force is known for each situation. However, the magnitudes of a few of the individual forces are not known. Analyze each situation individually and determine the magnitude of the unknown forces. Then click the button to view...
