This page contains links to set of **notes** and **exercises** associated with a second course in rigid body dynamics. The notes cover topics relevant to two-dimensional and three-dimensional motion. A more complete presentation of three-dimensional, rigid body dynamics is provided by the 3D Dynamics eBook.

A set of exercises with answers are provided at the bottom of this page. Two of the exercises recommend practice with MATLAB/Simulink/SimMechanics®.
