   In the animation:   
   https://www.geogebra.org/m/nwjkxbpk   
   by clicking on the appropriate button, the blue force of the hand   
   acting on body A is activated.   
      
   And that's the action.   
      
   In response to the force of the hand, the red reaction force of body A   
   on the hand is activated (according to the third principle).   
      
   Is it correct to say that the red force is inertial because to oppose   
   the force of the hand there is only the inertia of the body a?
