## Uniform Circular Motion

#### Activity Overview

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

#### Key Steps

• 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.

• 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.
