Neither Logger Pro nor Vernier Video Analysis automatically creates x and y acceleration columns for video analysis projects. We chose not to create acceleration columns automatically because the quality of video analysis position data is generally not as high as analogous motion sensor data. Position resolution may be poor due to a limited number of pixels, a small screen used for analysis, and the imprecision of a finger on a touch surface. When calculating derivatives, data noise is amplified. Velocity calculations are generally acceptable (except at the initial and final few velocity points), but the second derivative calculation is often unacceptably noisy.

If you want to see acceleration data, you will need to create x and y acceleration columns from the position or velocity data columns, using standard methods for creation of calculated columns.

Example Acceleration Column Expressions
● X Acceleration — secondDerivative(“X”,”Time”)
● Y Acceleration — secondDerivative(“Y”,”Time”)

Once acceleration columns exist, they can be graphed.
