+Learning Objectives
+===================
+
+After completing this chapter readers will be able to:
+
+- evaluate equations of motion numerically
+- numerically integrate the ordinary differential equations of a multibody
+  system
+- plot the system's state trajectories versus time
+- compare integration methods to observe integration error
+- create a simple animation of the motion of the multibody system
