In this episode on seesaws, we're looking at objects that can exhibit rotational ... and so, I'm violating Newton's 1st Law of rotational motion by doing the twist.. Sometimes we're slackers. But, right now, are you doing work? And what do we mean by work? Work -- the process of moving an object by applying a force.. Torque, moment, moment of force, rotational force or "turning effect" is the rotational equivalent of linear force. The concept originated with the studies by Archimedes of the usage of levers. Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object. ... If a force is allowed to act through a distance, it is doing mechanical work..
