      How do I use VelocityLab?

      VelocityLab can be used with PocketLab Voyager to turn to measure the position, velocity, and acceleration of a rotating object

      What is VelocityLab

      VelocityLab is a feature of PocketLab Notebook that works with PocketLab Voyager to measure the position, velocity, and acceleration of a rolling object like the wheel of a cart, the tire on a bike, or simply a can of soup. 


      Find some wheels and attach your PocketLab

      You can use VelocityLab with anything that rolls. A can of soup works great. Attach your PocketLab Voyager, connect to the VelocityLab app, follow the prompts, and you’re off.

      It’s easiest to attach your PocketLab to the side of your wheels or soup can so that it rotates about the z-axis like shown in the diagram below. 

      VelocityLab

      Roll the wheels or soup can down an incline. As they travel, you should observe an increase in velocity/positive acceleration caused by a net force from gravity. When the wheels reach the end of the ramp and travel on a flat surface, you should see a decrease in velocity/negative acceleration caused by a net force from friction.
