Explore the application of Newton's Laws to tension and pulley problems in this comprehensive physics lesson. Begin with tension problems, learning the definition of tension force and how to incorporate it into free body diagrams and net force equations. Practice with 1-dimensional and 2-dimensional tension problems, then tackle a two-body tension problem. Move on to pulley problems, starting with the mechanical advantage of pulley systems. Solve common two-body pulley problems by setting up net force equations to determine acceleration and tension. Progress through various practice problems, from basic to more complex scenarios, to solidify understanding of these crucial physics concepts.
