Intro to Angular Velocity

Submitted by PocketLab on Fri, 06/02/2017 - 18:24


We have previously learned that velocity is an object’s rate of change in displacement. Velocity is often measured as meters/second. Angular velocity however, measures the rate of change in the displacement of an object as it moves around a central point.

For example, the blade of a fan has angular velocity as it turns in a circle around the center of the fan. When an object moves in a circle around a central point the angular velocity is often measured as degrees/second. We can measure an object’s angular velocity in three dimensions along the object’s x-axis, y-axis, and z-axis.


In this experiment, students will: 1. Learn how to use PocketLab to measure angular velocity along all three axes. 2. Collect and analyze angular velocity data for a person moving in three dimensions and determine how different movements affect a person’s angular velocity. 3. Understand what angular velocity is and how it changes as objects move in three dimensions.
