A string is wrapped around a wheel and axle, draped over a pulley, and attached to a hanging mass.  The potential energy of the hanging mass is converted into rotational kinetic energy of the wheel and axle.

This is the Lab 9 Tier 1 Set-Up “A” of four set-ups. Each setup has a different combination of hanging mass, torque arm for the string and starting height of the hanging mass.
