In this activity, students create a situation that produces linear behavior by stepping heel to toe and taking distance readings as each step is taken. Students then apply the properties of a linear function to develop a model for motion.
This is Activity 2 from the Explorations book, TI-InterActive!™ Data Collection and Analysis (Texas Instruments Incorporated, 2000).
