Lab 1. Position and Velocity Graphs

We give the lab groups a position versus time graphs and from these they calculate what the velocity versus time graphs should look like, and then they plot these. They are then given a blank position versus time graph and they make there own graph, they again then calculate and graph these velocities to make another velocity versus time graph They then try to reproduce these graphs as best they can using the Vernier ULI UltraSonic Motion detectors. This is a good lab for students to observe the relationships between position, displacement and velocity. They also enjoy trying to reproduce the graphs.

The photo shows a student holding a board that the motion detector will monitor. The student then moves while a classmate records his position as a function of time using the program LoggerPro.
