The Acceleration Investigation is a great way for students to learn to create their own graphs of motion involving acceleration. The investigation leads students through the process of predicting what each type of motion will be like, then gathering data, plotting the points on a graph, drawing lines of best fit, and reaching conclusions about each type of motion.
This investigation can be done as a whole class, using one cart, or it can be done by separate lab groups with their own sets of equipment. The choice depends on the ability and maturity of the students. One ideal arrangement is to alternate between whole-class discussion for introductory questions, separate lab groups for data collection and graphing, and then returning to whole-class discussion for conclusions to each part of the investigation.
