This is a simple data collection lab to for students to use actual data that of themselves moving at a constant velocity. The purposes of the lab are as follows:

- Determine relation between distance and time during constant velocity.
- Graph the data collected and draw the "best fit" line.
- Analyze the best fit line to determine the equation and slope.
- Discover that the slope of a
*distance vs. time*graph is the average velocity. - Use the TI-83® to graph the data and determine the equation.
- Compare the results of conventional methods and those using technology.

As planned, the students will be gathering this data after completing the Graph Matching lab. To allow enough time for both labs to be completed, students should be able to print out the data for later use. If this is not an option, additional time may be necessary. Once again, as with all labs using the motion detector, be sure the students understand the limitations of the detector as listed in the previous lab.

The students will only be doing the data collection in class. The graphing and analysis will be done in the student's algebra class.

Make sure that each student takes their own data to analyze.

Extra sets of data are helpful for those students that are absent and need the data for algebra the next day.
