The algorithm for such derivatives utilizes a user-defined number of points. The default value of seven points is good for many experiments, but you may want to choose a larger number for human-scale Motion Detector experiments (e.g., our Motion Match lab), or a smaller number for cart-based Motion Detector experiments (e.g., our Impulse and Momentum experiment).
  • Page 19 ® LabQuest 2 – User Manual Data-Collection Summary A summary of the data-collection settings (Mode, Rate, Duration) is shown in the panel to the right of the Meter screen.
