Lab 5: Tier 1

A string is wrapped around a wheel and axle, draped over a pulley and attached to a hanging mass. When the mass is released it accelerates down. This acceleration is found. The calculations for this lab are intensive. There are conversions from inches to cm and a system of equations is solved using substitution.

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.
