Introduction to Rotational Motion

Introduction to Rotational Motion

Author: Felix Olsson
  • State the definition of angular displacement, angular velocity and angular acceleration of a rotating rigid body.
  • Relate these rotational quantities to the translational motion of a point on the rigid body.
  • Apply the kinematic equations for rotational motion to problems involving uniform angular acceleration.

This tutorial goes over the basic definitions for rotational motion. It relates to the first part of the rotational motion section of the notes.
