Atwood's machine is the name of a device that looks like this: Also known as "two masses on a pulley". Surprisingly, this simple device comes up a lot in intro physics texts. It also brings up some ...

A hands-on physics experiment demonstrates how a basic self-braking pulley works, explaining the forces and friction that allow it to stop itself without extra mechanisms. What happened with the 14th ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...
