What about objects that belong to other objects?
Many objects are composed of other objects.
It isn't necessary for you to individually control the motion of every object that is a part of a larger object.

However, if needed, you can control the motion of the component objects in addition to the motion of the object to which they belong.
For example, you could cause the ice skater to:
This would have her skating on one foot.
