参考答案:
A
non-rigid body cannot be described by a single value of angular velocity. Since the body is non-rigid, the angular
position of one part of the body changes with respect to other parts of the
body. Consider the solar system as an
example of a non-rigid body or system.
Each planet orbits in basically the same direction around the Sun, but
each planet has its own angular velocity which is different than that of the
other planets.
