LoggerPro3 Video Analysis
We used the video analysis component of Vernier’s LoggerPro3 software to collect data from both a constant motion vehicle. The video was advanced frame by frame and data points were selected. A scale was then set using the meter stick in the image. From here LoggerPro’s spreadsheet program was used for analysis. Results included: Continue reading LoggerPro3 Video Analysis
