Purpose: To measure the position of a ball as a function of time and to analyze the motion using graphical analysis.
Materials: Tennis ball, stopwatch, ruler, chalk, Graphical Analysis
Procedure:
Roll a tennis ball for five seconds down an incline, marking its position at each second with chalk.
Measure these positions as distances from the starting point and enter the data in the data table.
Plot a position versus time graph using Graphical Analysis.
