 We can actually consider the motion of any extended mass to be composed of different kinds of motion with respect to the center of mass. We can actually consider the motion of any extended mass to be composed of different kinds of motion with respect to the center of mass.
  
-So far we have dealt with translational motion, and we can now make explicit our implicit assumption till now that we consider the translation motion of an object'​s center of mass. We will now also see in the coming lectures that we can add to this translational motion other motions of the mass around the center of mass, for example rotational or vibrational motion.+We will now make explicit our implicit assumption till now that we consider the translation motion of an object'​s center of mass.
