Atwood Machine

Simple and effective, the Atwood machine cuts down on prep time and lets students dig into their experiments right away. Use this device with basic knowledge of classical physics to: derive a constant acceleration equation determine acceleration due to gravity verify laws of motion with constant acceleration investigate methods of determining tension in a string This Atwood machine uses robust materials and two 50 mm low-friction ball bearing pulleys. The pulleys are joined with an aluminum rod, making the device easy to mount to any ring stand. Students can easily measure the time of the drop with manual stopwatches or set up photogates to more accurately determine time over a known distance.
