Rolling Motion and Energy October 24, 2010 4 Physics 131 - Lecture 22
Rotational Energy A rotating rigid body has kinetic energy because all atoms in the object are in motion. The kinetic energy due to rotation is called rotational kinetic energy. Here the quantity I is called the object’s moment of inertia. The units of moment of inertia are kg m 2 . An object’s moment of inertia depends on the axis of rotation.

EXAMPLE 12.5 The speed of a rotating rod October 24, 2010 7 Physics 131 - Lecture 22 A 1.0 meter long, 200 g rod is  hinged at one end and connected to  a wall. It is held out horizontally,  then released. What is the speed of  the tip of the rod as it hits the  wall? Assume the hinge is  frictionless. Draw a before and after picture and choose an appropriate coordinate  system.
