When a particle rotates in a circle, its linear speed is
equal to the product of the angular speed and the radius.
For a rotating rigid body, at any given instant, every part
of the body rotates with the same angular speed, but different
parts may have different linear speeds.
For constant angular acceleration, we may write simple
equations that connect the angular displacement, angular
velocity, angular acceleration, and time.
The kinetic energy of a rotating rigid body is given by
Iw2/2, where I is the moment of inertia of the rigid
body, and w is its angular velocity.
The moment of inertia of a rigid body depends on its mass
and shape. For highly symmetric objects such as rods, rings,
disks, cylinders, and spheres, simple formulas for the moment
of inertia may be easily obtained.
