The Atwood Machine.

The Atwood machine (or Atwood's machine) was invented in 1784 by the English mathematician George Atwood as a laboratory experiment to verify the mechanical laws of motion with constant acceleration. Atwood's machine is a common classroom demonstration used to illustrate principles of classical mechanics.

MCLA Physics also has available a Pasco style Atwood Machine that can be interfaced with the the Capstone 850 Universal Interface.

This will allow the Instructor to derive the equations of motion of the Atwood Machine and then compare the results with what is captured by the Capstone software.

Capstone is available on most MCLA Physics lab computers.
