4.4 Tension Force and Pulley Problems | Application of Newton's Laws of Motion | General Physics

Tension Force and Pulleys
Chad provides a lesson on the application of Newton's Laws to Tension Problems and Pulley Problems. He starts with Tension problems and first provides a working definition of tension force and then explains how to incorporate tension forces into free body diagrams and net force equations. He begins with 1-dimensional tension practice problems before moving on to a 2-dimensional tension practice problem and then concludes this portion of the lesson with a two body tension problem.

Chad moves on to Pulleys Problems starting with a problem that demonstrates the mechanical advantage of a system of pulleys. He then moves on to common two body pulley problems showing how to properly set up a system of net force equations for which acceleration and tension force can be solved.
