This physics video tutorial provides a basic introduction into rotational motion. It describes the difference between linear motion or translational motion and rotational motion. It provides the formulas and equations for angular velocity given angular displacement, linear velocity given distance and time, frequency, period, tangential acceleration, angular acceleration, and centripetal acceleration.
