Rotation of Rigid Bodies
The angular velocity and angular acceleration are vectors.
Follow the right hand rule.
All the formulas obtained for constant linear acceleration are valid for the analog quantities to translational motion
Therefore, this is valid in general.
Rotational motion of a rigid body
Moments of inertia for various rigid bodies are given in section 9.6
Rotational kinetic energy is obtained by summing kinetic energies of each particles.
Each particle satisfies Work-Energy theorem
Work-Energy theorem holds true for rotational kinetic energy
includes rotational kinetic energy
Moments of inertia depends on the axis of rotation.
There is a simple relationship between Icm and IP if the two axes are parallel to each other.
Two axes of rotation
