## Vernier - Graphing Your Motion with EasyData™ App and CBR 2™

#### Activity Overview

Students will use a CBR 2™ motion detector to measure distance and velocity. Students prepare graphs of motion and analyze them. They compare and match graphs of distance versus time and velocity versus time.

#### Before the Activity

• If you are using a TI-84 Plus connect the CBR 2™ Motion Detector using a Unit-to-CBR 2™ cable, the EasyData App will start automatically
• If you are using a TI-83 Plus connect the CBR 2™ Motion Detector using Unit-to-Unit Cable and start the EasyData App
• Position the Motion Detector on a table facing an area free of objects
• See the attached PDF file for detailed instructions for this activity
• Print pages 11-13 from the attached PDF file for your class
• #### During the Activity

• Distribute the pages to your class
• Mark distances of 1-m, 2-m, 3-m and 4-m from the Motion Detector on the floor
• Starting with the 1-m position make students walk to different positions at varying speeds
• Plot a graph of distance versus time
• Examine a randomly generated graph and plan motion required to match it
• Explore making velocity versus time graphs and compare them with distance versus time graphs
• #### After the Activity

Students will complete the Student Data Collection and Analysis Worksheet.

Review student results:

• As a class, discuss questions that appeared to be more challenging
• Re-teach concepts as necessary
