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 both visually and verbally, including the values and units needed for calculations. What the information represents is also explained to the student.
