Procedure
The experimental variables for this experiment are position and time.
1. Set up the measurement board on the stand.
2. Put the camera as close as you can to the board but far enough away that you can see the enitre board.
3. Record the car as it moves past the board.
4. Use a video program on the computer that allows you to measure the position at different time intervals and do so.

Conclusion
The purpose of this lab was to calculate and graph position v. time and velocity v. time functions using a "real world" context while also learning to use video to take measurements. Some questionable results are the position and time data. They are questionable because there is too much room for human error trying to measure exactly where the car is when you are measuring it from such a small screen.
