Uniform Circular Motion

Published on 08/15/2010

Activity Overview

Students explore uniform circular motion and solve problems that deal with kinematics and dynamics of this motion.

Key Steps

  • Image

    Students investigate uniform circular motion. They determine the relationship between the radius of a circular path, the velocity of the

    object moving along the path, and the object's angular acceleration.

     

    First, students examine an animation of an object moving in a circular path. Vectors show the object's velocity and acceleration at each point on the path.

  • Image

    Students vary the radius of the circle while keeping the velocity constant. The data are graphed, and students use the graph to infer the relationship between acceleration and radius.

    Finally, students use this equation to solve several problems involving uniform circular motion.
