A cart is released from rest at the top of an incline. The maximum velocity attained by the cart is found from a velocity vs. time graph to be compared with the velocity that can be found using energy.

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 visually without a verbal description of what the data represents.
