 What is particularly important here is that you are able to determine the total work that is done by different forces acting on the system. Each force might act through a different displacement, so you will have to keep track of that when calculating the total force. The total energy of the system may take many forms: translational, rotational, and vibrational kinetic energy, as well as potential and thermal forms.
-In the real system, you need information about each force, the point of application of each force, and the distance through which each forces acts. From the real system, you gain information about the total energy of the system.

 In the point particle system, you need information about the net force and the center of mass; the point of application of the net force is the center of mass and it acts through the displacement of the center of mass. From the point particle system, you gain information about the translational kinetic energy of the system only.
