Lab 9: Tier 2

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.

In the video, the lab is performed followed by the data being presented on a graph, which students use to complete a lab sheet. When the graph is displayed, all the data needed to complete the sheet is presented both visually and verbally, including the values and units needed for calculations. What the information represents is also explained to the student.
