A cart is sent across a level track to collide into a bumper. The average force that the bumper exerts on the cart is found.

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.
