Introduction to Free Body Diagrams or Force Diagrams

The video tutorial introduces free-body diagrams, explaining their importance in physics problems involving forces. It demonstrates how to draw a free-body diagram for a book, identifying forces such as gravity, normal force, applied force, and friction. The tutorial also covers the concept of force vectors and their representation through arrows. Additionally, it explores how these forces interact when the book is on an incline, emphasizing the role of friction in preventing motion.
