This was a short activity where an accelerometer was attached to a spinning pedestal. The pedestal was then spun at different angular velocities and the sensor recorded how fast the pedestal was spinning. As the pedestal spun, the period was measured using stopwatches and an average was taken. The acceleration, period, and angular acceleration were recorded in a data table and graphed in LoggerPro.
The slope of the graph turns out to be the radius of the spinning pedestal. This value was compared to the actual radius distance and was found to have a very small percent error. The experiment was successful and the idea that angular acceleration and angular velocity are related was proven.
