Procedure
1. Set up pendulum and equipment to measure distance from center.
2. Start recording at an adequate distance away to still see the weight and meter stick clearly.
3. Release weight from a height an appropriate distance away and record video for at least 4 complete cycles.
4. Analyze video using Logger Pro and Excel and get time versus distance from center data.
5. Calculate the period

Data Analysis
Conclusion
The objectives of this lab were finally completed by developing the sinusoidal equations of motion for a pendulum. The experimental period and the calculated period were compared and the percent error was calculated to be 0.04408 % There was definitely a small percent error. This was probably because I picked a very specific spot on the mass and made that spot the position for the given time interval. Although there is still slight human error in the experiment. Another problem that could have resulted in error was the video pictures of each frame were blurry and prevented what could have been a more accurate reading of the masses position.
