Atwoods Machine Problems: describes a method for solving atwood machine problems when the pulley's mass is negligible. There are 190 free videos to help you understand AP physics at http://www.apphysicslectures.com ... This video assumes the mass is negligible (i.e., the rotational inertia of the pulley is near zero). It can also represent a problem with a massive pulley that offers no friction between itself and the string so that the pulley does not turn. For a video that gives the details of what to do when the pulley is massive see http://www.youtube.com/watch?v=h6Q0Lq...
