Lab 2: Tier 1

In the lab a cart is pulled across a level track by a hanging mass. Students determine the acceleration from a velocity vs. time graph and compare this with the acceleration that can be found using dynamics.

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.
