« Previous | Next »


Learning Objectives

  • Recognize analogies between rotational motion and translational motion.
  • Explain why the motion of a rigid body can be regarded as a combination of translation of the center of mass and rotation about an axis through the center of mass.
  • Be able to analyze problems involving rotation and translation using the energy method.
