Objectives: Collect position, velocity, and acceleration data as a ball travels straight up and down. Analyze position vs. time, velocity vs. time, and acceleration vs. time graphs. Determine the best-fit equations for the position vs. time and velocity vs. time graph Determine the mean acceleration from the acceleration vs. time graph Preliminary Questions: 1. Consider the motion of a ball as it travels straight up and down in free fall. Sketch your prediction for the position vs. time graph. Describe in words what this graph means.
