: dynamics,kinetics,mechanics
: Mechanics is a branch of the physical sciences that is concerned with the
: state of rest or motion of bodies subjected to the action of forces.
: The mechanics of righd bodies is divided into two areas:statics and dynamics.
: Statics is concerned with the equilbrium of a body that is either at
: rest or moves with constant velocity. The foregoing treatment is concerned
: with dynamics which deals with the accelerated motion of a body.
: Here the subject of dynamics will be presented in two parts: Kinematics, which
: treats only the geometric aspects of the motion, and Kinetics, which is the
: analysis of the forces causing the motion.
: From R.C Hibbler Engineering Mechanics Dynamics, P3-Introduction.
: As this result, we can defind a branch-diagram for yours question:
: Electronics, Thermodynamics, Electromagnetics, Optics
