Introduction to Free Body Diagrams

The video tutorial explains free body diagrams, which are sketches showing all forces acting on an object. It covers the steps to create these diagrams, including identifying the free body, sketching it, and labeling external and reaction forces. The tutorial also discusses the importance of coordinate axes for analysis and problem-solving, and how to apply Newton's second law to solve problems. Finally, it recaps the process of creating a free body diagram and its applications in statics and dynamics.
