Free-body diagrams are crucial in physics for understanding the forces acting on an object. They depict forces as vectors and are used to analyze motion and equilibrium. Key forces include gravity, normal force, friction, and tension. Newton's second law is fundamental in these diagrams, which are vital for students learning mechanics and solving complex physics problems.
