Old Classic Atwood

So for this blog,  I thought we'd go back or an old classic: the Atwood machine. We've been looking at and studying Atwood's for 2 years now. Let me explain to you what I know. So first, let me tell you what an Atwood machine is. So on each side of the machine, there is a hanging mass of whatever weight, not always equal on both sides. And hanging those weights is one thing that connects one mass,  wraps around a circular object,  then is connected to the other mass. So, the masses hang from the same string. Virtually, with no friction,  the only forces acting on each mass is the gravitational force down and the tension in the string up. With an Atwood machine, you can find an unknown mass of an object, you can find the tension in the string, many things you can find with just two hanging masses. So that's all for today on the Atwood. Now go out and by yourself one today. Tune in next time for more physics phun.
